can not be a determinant factor in structure damage. The micro-structural damage is due to disintegration of mineral aggregates, leading to changes in the number and size of cracks and pores. The damage...The Quantification of Micro-structural Damage of Weak Muddy Intercalation in Dry-wet Cycles Combining in-situ SEM and DIP何乐平,ZHONG Lin,胡启军,GU Yucheng,ZENG Junsen,TANG WeiSchool of Civil Engineering......
factor of tunnel rock mass considering the damage and reinforcement effect was founded to study the stability state of rock mass. The numerical calculation software FLAC3D with the internal FISH... the same, which validates the correctness of the deduced equation for the element safety factor based on the Barton criterion parameters and the program built. Key words: tunnel rock mass; damage; grouting......
Visco-elastoplastic damage constitutive model for compressed asphalt masticZENG Guo-wei(曾国伟)1, 2, YANG Xin-hua(杨新华)1, BAI Fan(白凡)1, GAO Hu(高虎)1(1. School of Civil Engineering and Mechanics, Huazhong... behavior of compressed asphalt mastic, a visco-elastoplastic damage constitutive model is proposed in this work. The model parameters are treated as quadratic polynomial functions with respect to stress......
Thermal-hydro-mechanical coupling damage model of brittle rockLI Peng(李鹏), RAO Qiu-hua(饶秋华), LI Zhuo(李卓), MA Wen-bo(马雯波), MA Bin(马彬)(School of Civil Engineering, Central South University, Changsha 410075, China)Abstract:Based on fluid mechanics, thermodynamics and damage mechanics, thermal-hydro-mechanical (THM) coupling damage model of brittle rock is established by analyzing THM coupling......

Protective effects of Rad23 protein on ultraviolet damage to HeLa cellsLI Xiu-shan(李秀山), ZHANG Ji-hong(张继红), ZHAO Xiao-ying(赵小英), LIU Xuan-ming(刘选明) (State Key Laboratory of Chemo/Biosensiny and Chemometrics (Bioenergy and Biomaterial Research Center,College of Biology, Hunan University), Changsha 410082, China)Abstract:Protein Rad23, a nucleotide excision repair factor, mainly involves......
Damage statistical mechanics model of top coal in steep top caving coalPingwu Shi, Xingping Lai, and Zhaoning GaoSchool of Enengy, Xi’an University of Science & Technology, Xi’an 710054, ChinaDept. of Resources Exploration & Management Engineering, Anhui University Science and Technology, Huainan 232001, China摘 要:<正> Damage statistical......
, the damage factor (the plastic shear strain) of each rock sample gradually increases with the increase of post-peak cyclic loading and unloading period, and the crack damage stress of each rock sample... [32] was used, which adopted the plastic shear strain of rock to define the damage factor, and its value can be obtained by ......
