【摘要】 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。更多还原

【Abstract】 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. Through thickness weighted average and deformation equivalence,the horizontal and vertical deformation modula of synthetic rock mass are obtained.更多还原
