Authors: Zhang Zhe , Wang Teng 
Published: June 2019

Abstract
The pile foundation is often affected by friction fatigue during pile installation and cyclic loading. In order to study the fatigue behavior of it, the installation and cyclic experiments were carried out using pile foundation model test device. The effects of cycle numbers, cumulative displacement on the pile load performance were studied in the experiments. The results show that the friction fatigue appears with different degrees on pile installation and cyclic process. During installation from soil surface, the soil plug increases and eventually remains constant, and the pile head load increases with the increase of penetration displacement, while the horizontal stress on pile shaft decreased with the increase of h/R because of lower relative displacement. In the cyclic load stage, pile head load and base resistance stresses decrease rapidly in the 5 cycles and gradually restore to 68% and 112% respectively, while the horizontal stress reduces to stable in cyclic load and the fatigue behavior is more significant with lower value of h/R due to the higher degree of soil particle breakage.

Abstract
The Red-bed soft rock is widely distributed in South China, and it has been exposed to acid rain for a long time, which brings great risks to the stability of the engineerings. Therefore, the Red-bed soft rock in South China is selected as the research object. A disintegration test under acidic environment was carried out, and the law of grain size change during disintegration is obtained. The reaserch shows that: (1) Disintegration is a process in which large particles gradually transform into small particles; (2) Acidic environment promotes the disintegration of Red-bed soft rock, and the stronger the acidity, the stronger the disintegration; (3) In acidic environment, the disintegration of Red-bed soft rock can be divided into three stages: water absorption stage, rapid disintegration stage and slow disintegration stage; (4) Red-bed soft rock disintegration to different acidic solutions is different, which HNO3 dominates the disintegration than H2SO4; (5) Due to the dissolution of mud, the main minerals participate in the reaction, causing rock cementation loss withpores larger, and finally lead to the softening and disintegration of the Red-bed soft rock.

Authors: Ren Jinghui 
Published: June 2019

Abstract
The application of Artificial Intelligence techniques on data mining as well as semantic studies has given rise to new discoveries over the research of lexicons in English for Specific Purposes (ESP). The present paper, assisted by the corpus software, carries out a data mining research on the lexical co-occurrence features and explores an empirical study of semantic preferences in Construction Engineering English. The semantic co-occurrence research has been conducted from three aspects involving lexical categories, lexical collocations and lexical colligations. With data retrieval and context analysis, the present research has found out that the lexical categories of Construction Engineering English are limited to seven fields, which are chemical substance, construction materials, structures, positions & measurement, natural environment, living environment and force. Besides, lexicons in different categories demonstrate distinctive semantic preferences and collocation features. And the semantic colligations of Construction Engineering lexicons are majorly neutral in semantic preference, which further proves the neutral and objective characteristics of technology articles.

Authors: Shen Bin Xian , Liu Wei Qiang 
Published: June 2019

Abstract
The hot fuel gas generating with solid fuel was introduced to an opposing jet thermal protection system(TPS), saving the occupied space and reducing the weight of the gas supply system. In this study, the thermal protection performance of opposing jet TPS with hot fuel gas is investigated. The surface heat flux is initially obtained by solving the Reynolds-average Navier-Stokes(RANS) equations coupled with the Menter’s shear stress transport (SST) model. Then, the obtained heat flux is loaded to the blunt body to solve the temperature distribution. The influence of the hot fuel gas on the opposing jet TPS was analyzed with different flying condition. Results show that the hot fuel gas reduces the insulating capacity of the opposing jet, but the peak heat flux exhibits a prominent reduction in contrast to that without injection. The surface temperature also reduces a lot even the hot fuel gas is adopted than that without injection. To obtain a good cooling efficiency, the jet pressure is enhanced. With a higher jet pressure, the surface heat flux, as well as the surface temperature, is reduced, and the similar cooling efficiency can be obtained compared to that with normal coolant.

Published: June 2019

Abstract
Offshore oil-gas platforms in the same area are generally connected through the power grid and subsea oil-gas pipeline networks. It has formed a typical integrated energy system which interacts with multiple energy sources, water, electricity, gas and oil. However, the traditional energy management research mainly focuses on the stability control of the platform’s power network, and does not model the energy system of the platform group as a whole, which cannot reflect the characteristics of energy interaction between the platform groups. Therefore, this paper combs the current situation of energy utilization and operation control of offshore oil-gas platform energy system in a sea area of China, establishes the energy network of offshore oil-gas platform group, and puts forward the modelling, analysis and optimization method of offshore oil platform group. Firstly, focusing on the main energy coupling equipment (gas power station, gas heat station, electric heater,) of the platform, the energy efficiency analysis model is established to realize the energy efficiency diagnosis of the equipment. Then, based on the theory of Energy Hub, an electro-gas interaction optimization scheduling method is proposed to realize the optimization analysis of energy interaction between platforms. Finally, a calculation example of the actual platform group is given, which consists of three power generation platforms in China. The relevant research results will guide the closed-loop management of the operation, optimization and evaluation of the energy system. The application in the integrated energy management system of offshore oil-gas platform is helpful to improve the energy integration control of offshore oil platform.
