摘要
本文由节理和岩块体变形迭加的方法推导出节理岩体的应力—应变关系式,并分析了各种节理和岩块体破坏的组合形式及其变形状态,因而能较准确地反映节理岩体的破坏机理。
This peper has given a stress—strarin relationship of joint rocks, of which the expression has been deduced by using the iterative addition of dformation of joints that wewe different positions respectively on the rock mass. As well as, this papes has analyzed possible combination of failure of joints and rock blocks. As a zcsult, the failure mechanism of the joint zock mass can be shown accurately.
