摘要
研究了岩体在拉剪应力作用下裂缝尖端的亚损伤区大小,以及亚损伤缝的长度-通过损伤分析,给出了损伤岩体的变形模量,以及损伤扩展的变形模量,并且将岩体的连通率与变形模量联系起来,这是对岩体力学损伤分析的有效补充。
The subdamaging zone and the length of subdamaging crack of rock mass crack tip under tension-shear are studied By damage analysis,the deformation modulus and the damaging deformation modulus of the damaged rock mass are given,The cracking rate related with the deformation modulus is made This is an effective supplement to rock mass mechanics.
