Transition Threshold of Granite Mechanical Characteristics at High Temperature by Hongjun Guo, Ming Ji, Dapeng Liu

“…The behavior of the increment ratio of strain, elastic modulus, Poisson’s ratio, and energy with axial pressure is analyzed, and the following conclusions are drawn. (1) High temperatures aggravate rock deterioration, reduce failure strength, and enhance ductility characteristics. (2) Under loading, the compression-to-elasticity and elasticity-to-plasticity transition thresholds for rock occur, respectively, at 20%–35% and 75%–80% stress levels at temperatures of 25–800°C. (3) The source data for calculating rock deformation parameters or unloading points for unloading tests can be selected over the stress level range of 35%–75%.…”

Spatial Difference Analysis of Water Resources Carrying Capacity in Henan Province by MIAO Zhiying, FENG Yi, LIU Debo

“…Taking 18 cities in Henan Province as the research objects,this paper selects 16 indicators from the water resources-society-economy-ecology composite system.Utilizing the entropy weight TOPSIS method,it conducts the spatial difference analysis and comprehensive evaluation of water resources carrying capacity on 18 cities in Henan Province in 2018.The evaluation results show that the water resources carrying capacity of Henan Province in 2018 is weak.From the perspective of spatial difference,the water resources carrying capacity is the strongest in the southern region,followed by the western region,and the northern and eastern regions are the weakest.Cities with descending water resources carrying capacity are as follows: Xinyang, Zhumadian, Nanyang, Zhengzhou, Sanmenxia, Luoyang, Pingdingshan, Shangqiu, Luohe, Jiyuan, Xuchang, Zhoukou, Anyang, Kaifeng,Hebi,Xinxiang,Jiaozuo,Puyang.The water resources subsystem and the economic subsystem have great influences on water resources carrying capacity in different cities.GDP,water production modulus,and precipitation affect the water resources carrying capacity most in 2018.…”
