Authors: Wang Yuying , Tang Jiajun , An Silong , Hu Jie 
Published: May 2021

Abstract
In order to study the optimal combination of mechanical properties of recycled aggregate concrete under the condition of multiple indexes, the orthogonal test results of recycled concrete were analyzed by queuing score method, taking the replacement rate of recycled aggregate, replacement rate of fly ash and incorporation rate of steel fiber as factors, and the compressive strength, splitting tensile strength, flexural strength, tension-compression ratio and flexural-compression ratio as indicators. The results show that the incorporation rate of steel fiber has the greatest influence on the mechanical properties of recycled aggregate concrete, followed by the replacement rate of fly ash, and finally the replacement rate of recycled aggregate. The optimum combination of recycled aggregate concrete is A4B2C4, that is, the replacement rate of recycled aggregate is 100%, the replacement rate of fly ash is 10%, and the incorporation rate of steel fiber is 1.8%. Queuing score method can accurately determine the influence of factors on recycled aggregate concrete and optimal combination in orthogonal tests.

Published: May 2021

Abstract
In order to explore the influence of sloping roofs on the indoor thermal environment in cold regions in summer, the article takes the sloping roofs and flat roofs of traditional houses in a county in the cold region of Weinan City as the research object. A combination of theoretical and field measurements was used to analyse the effect of sloping roofs on the internal and external surface temperature of the floor level, indoor temperature and humidity, and comfort in summer. The results show that the existence of sloping roofs largely reduces the surface temperature of the roof and the heat transfer from outdoors to indoors, and can reduce the indoor air temperature by 1.3°C compared to flat roofs, which has a good effect of stabilising the temperature change and keeping the indoor thermal sense in a warm state, and the results of the study can provide a scientific basis for the construction and application of sloping roof houses.

Abstract
Hemerocallis is the mother flower of our country. It has a cultivation history of more than 3000 years. Hemerocallis culture has a long history and has a profound influence throughout the country. As a tool and technical means of cultural communication, the media plays an important role in the development of Hemerocallis culture. This paper uses the literature research method to explore the cultural origin of Hemerocallis, and analyze the influence of media communication on the cultural development of Hemerocallis. The ancient literati Sao Ke promoted the development of Hemerocallis culture through poems and songs, but the more influential communication media nowadays have not played a good integration role. This article aims to use the media to regain the day lily culture, to bring new enlightenment to the promotion and popularization of Chinese mother flowers, to explore how to apply it to the landscape, and to promote the traditional Chinese culture of filial piety.
Research on the Stability of Dam Foundation of a Sluice Dam Project in the Pearl River
Authors: Sun Tao , Yang Baoquan , Chen Yuan , Chen Jianye , Tan Chun 
Published: May 2021

Abstract
In water conservancy projects, the safety and stability of sluice dams are worth exploring due to the fact that they are subject to a wide variety of loads and the physical and mechanical properties of the dam foundation are easily weakened. This paper focuses on the study of the stability of the foundation of a dam project on the Pearl River when the strength and deformation characteristics of the weak interlayer are weakened. Through geomechanical model tests, two methods of overloading and strength reduction are used to explore the stability of the dam foundation of the dam. Whether the instability of the dam foundation of the sluice dam is deep sliding or shallow sliding, the deformation characteristics of weak interlayers in various parts under different overload multiples are explored. Tests show that only the weak interlayer at the surface is cracked and penetrated, and the deep weak interlayer is not obvious. It shows that when the weak interlayer and rock layer are weakened, only shallow damage occurs to the dam foundation and only targeted reinforcement measures are required. The research is not only critical to the safe operation of the sluice dam project, but also serves as a reference for other similar sluice projects.

Authors: He Liping , Wang Xuegang , Liu Zhijun , Teng Chao 
Published: May 2021

Abstract
This text selects subgrades filled underwater in the section of Taitema lake of an expressway project in Xinjiang. The underwater deep treatment of aeolian sand and gravelly soil subgrades were carried out by dynamic compaction, and excess pore water pressure of that was monitored during compaction. The consolidation effects after dynamic compaction were compared. The results showed that: After dynamic compaction, excess pore water pressure in subgrades of aeolian sand and gravel soil increases as the number of tamping, and dissipates quickly after tamping. The subgrade strength of aeolian sand and gravel soil is improved obviously after dynamic compaction, but the overall reinforcement effect of gravel soil subgrade is better than that of aeolian sand subgrade, so gravel soil should be chosen first when the subgrade is filled underwater.
Study on the particle size distribution characteristics and cementitious activity of different fineness components in cement
Authors: Yu Chaocheng , Zhang Yongping , Li Zaibo 
Published: May 2021

Abstract
In order to obtain the change law of the cementitious activity of the different fineness components in the Portland cement, the cement was classified by the air classifier and six components with different fineness were obtained. The particle size distributions of the six components were measured and their cementitious activities were evaluated. The results show that the cement powder obtained by classification basically conforms to the distribution model of Rosin-Rammler-Bennet equation. The fluidity of the mortar of different fineness components in cement does not change significantly with the change of fineness. The greater the fineness of each component is, the higher the early strength of their mortar test will be, but as the curing age increases, the strength increase is not obvious. The sample obtained by mixing three finer-grained components has the highest mortar compressive strength in the early age, and the strength increase in the later age is stable.

Published: May 2021

Abstract
Under the loading of earthquake, sandy soil is prone to liquefaction and resulting in the superstructure damage. Therefore, the liquefaction identification of sandy soil is the primary task of liquefaction disaster prevention. Based on the energy dissipation method, the relationship between pore water pressure (u) and dissipated energy density (W) of fiber-reinforced sand (FRS) is established, and the effects of fiber length (FL), fiber content (FC), cyclic stress ratio (CSR), and relative density (Dr) on the accumulation of u are analyzed. The results showed that fiber addition can effectively slow down the liquefaction of FRS, and the curve of u and W can be divided into rapid growth stage, stable ascend stage and slow growth stage. When the u keep constant, the W increases with the increasing of FL and FC. Whereas, the u decreases with the increasing of FL and FC when the W keep constant. The u and W are less affect by CSR, and the dense sand of FRS is less prone to liquefaction than loose sand.

Study on Comprehensive Evaluation Method for Construction Suitability of Precast Concrete Beam-column Connections
Authors: Jiang Wanliang , Du Bin 
Published: May 2021

Abstract
The key difference between prefabricated structure and cast-in-place structure is the connection of components. The comprehensive reliability of the connection directly determines the overall performance of the structure, and also affects its application scope in the building structure. It is particularly important to select the appropriate beam-column connections in the construction. In recent years, with the continuous development of precast concrete structure, a large number of precast beam-column connections have been invented. However, in view of different construction environment, construction cost and building function requirements, the selection of precast beam column connections is often difficult to choose. Therefore, this paper is based on the Analytical Hierarchy Process (AHP) evaluation model, combined with the evaluation index of the precast concrete beam-column connections, to provide a scientific method for selecting suitable precast beam-column connections for engineering construction.
Research on construction cracks of wide box girder
Authors: Sun Wenhuo , Li Pingjie 
Published: May 2021

Abstract
Based on the numerical simulation and field test, combined with the engineering case, this paper studies the causes of construction cracks in wide box girder, and proposes for the first time that the three-dimensional prestressed tendons tension sequence is an important cause of construction cracks in wide box girder. The research results show that: the hydration heat of concrete and the tension sequence of three-dimensional prestressed tendons are the two main reasons for the construction cracks of wide box girder. The lag tension construction technology of transverse and vertical prestressed tendons makes the tensile stress of bottom plate increase rapidly in the early stage of construction, and makes the tensile stress of web plate increase in the construction process, which leads to cracks pouring in the early stage of box girder, but the tension of prestressed tendon has little effect on the final state stress of box girder. The research results of this paper can be used for reference for the construction crack control of prestressed concrete box girder.

Authors: Xie Yaofeng , Zhan Tianxin , Fan Yue , Xu Shuangwu , Feng Hui 
Published: May 2021

Abstract
Based on the ANSYS model, the simulation analysis of the all-vertical-piled wharf is carried out. It is found that the zero point of the pile displacement of the all-vertical-piled wharf is about 6 times the depth of the pile width (pile diameter) below the mud surface. The difference in pile displacement changes under various working conditions below this position is very small, and the pile displacement above this position is positively correlated with the horizontal load. Through research, the pile displacement curve and load-displacement curve of the all-vertical-piled wharf are constructed, and the method for determining the overall ultimate bearing state of the all-vertical-piled wharf is established. The research results can provide a reference for the study and judgment of the overall bearing safety of the all-vertical-piled wharf under horizontal load.

Authors: Chen Hui-lin 
Published: May 2021

Abstract
Due to the increasing traffic load, existed bridges suffer from various diseases such as aging, cracking, excessive deflection, etc., which lead to the decrease of structural bearing capacity and a series of safety accidents. In this paper, various diseases of a 5 × 20m simply supported T-beam bridge are identified by routine bridge detection, and then the mechanism of diseases are also analyzed. According to the characteristics of the diseases, the reinforcement method with bonded steel plates is proposed. Finally, the static load test of bearing capacity to evaluate the strengthening effect of the bridge is carried out. The results show that the deformation law and strain state of the strengthened bridge structure are normal, the bearing capacity and rigidity of the structure meet the requirements of the design load standard, so the problem of insufficient shear and bending capacity of the simply supported T-beam bridge can be effectively improved by sticking steel plate. The research results have important engineering application value for improving the structural performance of existed bridges, promoting the sustainable development of existed bridges and saving economic costs.
