Through statistical investigation spacing, thickness and continuity of low angle weakness plane that existing quasi-lamellar structure basalt rock mass, we analyze the affect of this low angle weakness plane to rock mass strength parameter, and obtain the method of low angle weakness plane continuity.
通过对赋存于似层状结构玄武岩岩体中随机发育缓倾角软弱结构面的厚度、间距及连通状况的调查,分析了缓倾角软弱结构面对相应基本岩体强度参数各向异性的影响,并探讨了缓倾角软弱结构面连通率的求解方法,最后通过“连通率”和“厚度加权”法得到了水平和垂直的强度参数值。
By statistically analysing dip angle,linear density or spacing and thickness of the weak interfaces existing in quasi-lamellar structure basalt rock mass,the necessary weaking parameters of basic rock mass deformation modulus are obtained considering the effect of weak interbed thickness.
通过对赋存于似层状结构玄武岩岩体中随机发育缓倾角软弱结构面的发育特征,即厚度、密度或间距的统计分析,获取了对基本岩体变形模量考虑软弱结构面厚度效应的弱化参数,并通过“厚度加权”和“变形等效”法得到了水平方向和垂直方向的变形模量值。
