Authors: Jie Yong , Li Qin , Yiwe Li , Jingyi Li 
Published: May 2020

Abstract
The practice of fracture network fracturing in shale gas layers indicates that the formation of complex fracture networks is directly related to the probability of obtaining a sufficiently large reservoir to effectively rebuild the volume and the ability to obtain high economic benefits. With the continuous deepening of shale gas exploration and development, it is found that the current artificial fractures have slopes, branches and asymmetric distribution. As a result, the production difference between different horizontal wells in the same platform and different fracturing sections of the same horizontal well is obvious. How to optimize the exploration and development plan and promote the economical and effective development of shale gas resources is the most important problem currently facing. The post-evaluation technology of reservoir reconstruction effect has become a key technology. Therefore, it is of great production significance to carry out post-evaluation work by integrating multivariate data. This article takes the SiChuan WeiYuan Shale Gas Demonstration Area as an example, and uses microseismic results and surface seismic data, geology, logging, fracturing and production dynamics data to carry out fracturing fracture modeling and productivity prediction. Provided guidance for fracturing design optimization, development well location, well spacing deployment, and development effectiveness, with good application results.

Study on Risk Assessment of Inland Nuclear Power Investment Construction Projects by Kazakhstan
Authors: Liu Liangyan , Cheng Ming 
Published: May 2020

Abstract
This article is the first attempt to conduct a comprehensive evaluation of Kazakhstan’s inland nuclear power investment construction projects. Based on the summary of existing research results of scholars at home and abroad, a systematic analysis of the sustainable development model is made from the following four aspects to conduct safety evaluation research on domestic nuclear power construction in Kazakhstan: 1) Probabilistic safety evaluation for Kazakhstan’s inland nuclear power construction; 2) Public perceived risk evaluation for nuclear power construction in Kazakhstan; 3) Economic evaluation for recirculating systems of spent fuel; 4) Benefit risk evaluation for Kazakhstan’s inland nuclear power construction. Based on China’s multi-criteria decision analysis of dynamic system modeling, we add noise to the uncertain factors of the safety evaluation of Kazakhstan nuclear power investment projects and then perform noise reduction to refine our evaluation results. First of all, due to the non-convex optimization of tensor decomposition, there is no guarantee that the factorization will be determined by optimization. In addition, tensor decomposition can converge to different local optimal values corresponding to different initial values of the two tensors. Therefore, if the initialization value is set correctly, the result will be approximately optimal compared to the case where the initial value is far from the global optimal value.

Small temperature difference in the middle and later water cooling stages of RCC dam
Authors: Xue Yifeng , Cheng Handing , Yao Ge 
Published: May 2020

Abstract
Water cooling is the main measure to reduce temperature cracks in RCC dams. But later cooling usually means reducing water temperature rapidly after 120 days of the concrete age, which may cause larger self stress and tensile stress inside the concrete. The small temperature difference cooling can advance the starting time of middle and late cooling stages, and reduce the temperature stress effectively. However, the difference of temperature stress produced by different middle and late stages water cooling methods is large. It is necessary to analyse precisely how to use the small temperature difference methods in the middle and late cooling stages of dams properly. The cooling methods of RCC dam in the middle and late stages are studied by using the self-developed 3-D FEM floating mesh method temperature controlling simulation program. Result shows that when the small temperature difference is used to cool the dam in the middle and late stages, the temperature and temperature stress of the dam reduces obviously. When the age of the concrete is over, the dam should be cooled immediately, several levels of water temperature should be set in the middle and late cooling stages, the temperature of the water should be reduced slowly, which can reduce the temperature and temperature stress of the dam effectively. Study result will provide a favourable reference for practical projects.

Effect of rubber particles on dynamic mechanical properties of ultra-lightweight cement composites
Authors: Wang Fang , Sui Lili , Huang Zhenyu 
Published: May 2020

Abstract
This paper develops a novel rubberized ultra-lightweight cement composites (RULCC) incorporated with different amount of rubber particles and investigates the static and dynamic mechanical properties of the RULCC experimentally. This study shows that the rubber particles have significant effect on the compressive strength, stress-strain curve and failure mode of the RULCC. A volume replacement of fine aggregates with 10% and 20% rubber particles results in a reduction in static compressive strength and elastic modulu. The dynamic experiments show the RULCC is a strain-rate sensitive material and the dynamic stress-strain curves illustrate that the capcity of energy absorbtion of RULCC is better than the composites without rubber particles. The experimental and analytical studies are essential to better understand the fundamental dynamic behaviour of RULCC for its further applications.

Published: May 2020

Abstract
This paper proposes a novel full-scale square tubular-UHPFRC grouted connection for precast column-column connections. This study examines the mechanical properties of four full-scale square tubular columns fully-grouted or partially-grouted with UHPFRC via experimental and theoretical studies. The experimental program explores the ultimate resistance and failure modes of the grouted connection under axial compressive and tensile loads. The test results show that new column-column connections perform well in its resistance and stiffness while three main failure patterns include punching shear failure of end plate, welding fracture and local buckling of steel tube are observed. The theoretical model on resistance prediction explains the failure mechanisms of new connection well and it is instructive for the detail design of such novel grouted connection.

Abstract
In order to study the effect of early-stage concrete loading on the tensile strength of the later splitting, a total of 11 series of specimens were designed. Through the continuous pressure in early age, the effects of early bearing axial compression ratio, loaded time and concrete strength on the tensile strength of concrete during splitting were discussed.A set of sustained pressure device was set up, through which six concrete specimens could be applied continuous pressure force together. The test results show, when compression ratio is less than 0.5, the sustained pressure at early age has positive effect on the late splitting tensile strength. The increase range in the experimental parameters is between 3.7% and 24.5%.
