Authors: Huang Mingli , Sun Tong , Wang Linghai 
Published: July 2020

Abstract
Taking integrated pipe gallery of Tongzhou City Sub-center in Beijing as studied project, the research on the formulation of solidified soil and its preparation process were carried out for the silty clay and sandy soil samples on the site. The parameters were analyzed by finite element software simulation, which in results show that the ready-mixed fluidized solidified soil is characterized by high strength, self-compacting performance, impermeability, water stability, construction performance, and economic performance. It is in advanced compared with the traditional backfill materials. The application of solidified soil technology needs to be developed to adapt special equipment. After 7 days of placing the concrete structure, in view of factors of construction quality and construction period, the concrete structure is selected to be demolished for backfilling of the pre-mixed fluidized solidified soil, with single backfilling 0.5 meters and 1 meter respectively. The impermeability and water stability of the ready-mixed fluidized solidified soil are qualified. but the resistance to freezing and thawing is unacceptable. The mixed fluidized solidified soil should be backfilled in the area below the frozen soil layer.

Published: July 2020

Abstract
To investigate the 2D mechanical response of flexible buried pipelines beneath roadway under static loads, taken high-density polyethylene (PE) as an object, ANSYS finite element commercial software is employed to construct pipe-soil interacting coupled model. The influence of burial depth, the diameter of the pipe, and modulus of backfilled earth on the deformation of the pipe are studied with the newly developed model. These results indicate that: (1) the maximum vertical displacement and Von Mises stress appear at the top of pipe and side of the internal surface of the pipe, respectively; (2) even if burial depth does not have a significant effect on mechanical characteristics of pipe, there is optimal burial depth; (3) the higher the diameter of conduits, the larger modulus backfilled earth, the more difficult it is to destroy pipe breaks.

Published: July 2020

Abstract
Reinforced corrugated Steel retaining wall is a kind of retaining wall structure that can realize rapid construction. It has the characteristics of large strength, high rigidity, fast construction speed and small environmental disturbance. In this paper, the finite element model is established by using ABAQUS software. With the load of 80Kpa and 120Kpa at the top of the fill, the mechanical and deformation characteristics of the steel corrugated board are studied under the coupling of steel corrugated board and fill soil. The Horizontal deformation of corrugated panel and soil of different depths are analysed. Then the stability of the retaining wall structure are analysed. The research shows that the steel corrugated retaining wall presents a reverse “S” shape under the action of filling, the upper part presents an outward deformation, and the lower part presents an inward deformation extrusion soil; under the up load, the middle part of the retaining wall produces protrusions. As the load increases, the bulge increases with the tendency of the outward inclination. The stability analysis shows that the safety factor of the retaining wall structure under the load meets the requirements of relevant specifications.

Authors: Liu Dianyuan , Qi Tiedong 
Published: July 2020

Abstract
In order to study the sensitivity of construction control of multi span PC continuous beam bridge with corrugated steel webs, taking the main bridge of Yesheng Yellow River Highway Bridge in Ningxia as an example, the space finite element analysis software is used to simulate the bridge and calculate the construction control. In the process, different values of the main parameters of the structure affect the degree of the linear and internal stress of the bridge. The calculation results show that the effects of shrinkage and creep of concrete roof and floor, segmental weight and temperature gradient on the deformation and stress of the main beam are obvious; the elastic modulus of the concrete has a certain degree of influence on the deformation and stress of the main beam, and the influence of the prestressing parameters is smaller. Therefore, in the process of construction control, the influence of shrinkage and creep of the concrete roof and floor shall be considered, the weight of the main beam shall be strictly controlled, and the effect of the measurement time and the temperature gradient effect shall be taken into account in the linear monitoring.

Authors: Wang Zhi-yuan , Chen Hai-ting , Ou Yang-mei 
Published: July 2020

Abstract
Regional urban connection is mainly reflected in the connection between transportation and economy. Using accessibility and improved gravity model, this paper studies the traffic and economic relations and spatial pattern analysis among districts and counties in Hengyang based on the shortest travel time data and socio-economic data of 12 districts and counties in Hengyang, China. The results show that: firstly, in terms of traffic accessibility, there are 8 districts and counties in Hengyang that have higher accessibility than the average level of the city, and 4 districts and counties that have lower accessibility than the average level. Secondly, the accessibility of districts and counties in Hengyang generally presents an irregular circular distribution pattern, forming a core edge distribution feature with five districts in Hengyang as the core and gradually decreasing outward enclosure. Thirdly, from the perspective of economic connection, the 12 districts and counties in Hengyang are divided into five levels. The first level is the connection between Shigu District and Yanfeng District in the central city. The second level connection intensity is between Shigu District and Zhengxiang District in the central city and between Zhengxiang District and Hengyang County. The intensity of the three-level connection is the connection between the counties near the central urban area and the districts in the central urban area, as well as the connection between the counties near the central urban area and the neighboring counties. The fourth level connection refers to the connection between districts and counties far away from the central urban area and counties near the central urban area. The fifth level connection refers to the connection between districts and counties far away from the central urban area.
Last but not least, the economic connection of Hengyang District and county forms the center-peripheral radiation pattern which diffuses from the area with the core of Shigu District, steamed Xiang District, Yanfeng District and Zhuhui District as the core, which presents the pattern of “one core and two centers” in space.

Abstract
The color of a residential area landscape not only provides an intuitive reflection of the city image but also significantly influences residential experience. Based on the Munsell Color System, this study uses color card comparison quantification and a questionnaire to conduct a sample survey and quantitative analysis of the color of residential landscape areas in Shenyang. The results indicate the following: (1) Buildings are dominated by a warm color of middle–high value and middle–low chroma. The pavement has a predominantly neutral color or warm color of middle value and middle–low chroma. Landscape facilities mainly has a warm color of middle value and middle–low chroma. The dominant hues of landscape plants in spring, summer, and autumn are purple–red, green–yellow, and red–yellow, respectively; (2) Residents are more satisfied with landscape facilities and plant colors than with buildings and pavements. They expect artificial landscape colors to create a warm, bright, soft, pleasant, and intimate ambience; (3) Cool or neutral colors are avoided in large-scale Shenyang residential areas. Colors with a value of 4–9 and chroma of 1–5 are recommended; simultaneously, embellishment with other hues and an appropriate increase in colored plants may be applied in garden landscaping.
