摘要
使用刚体极限平衡法，通过建立分类座标系，导出了由三个结构面和一个临空面组成的四面体岩坡在任意外荷载作用下，结构面上正压力、滑动力的统一表达式。据此，可方便地判别岩坡的滑动类型，进行岩坡滑动分析。本算法较为简洁，能考虑结构面上凝聚力对岩坡滑动的影响。
Applying the balance method of rigid-body limit and through establishing a sorting ccordi-nate system,this paper derives an unified expression for positive pressure and sliding force on structure5urfaces of rock mass which consists of three structure surfaces and a aerial surface under the action ofoptional external load.In View of the above,we may conveniently distingush the siding pattern ofrock slope and make a sliding analysis of rock slope. This calculating method is relatively terse and theeffect of cohesion on structure surfaces on rockslope sliding can be considered.In engineering,there isa definite practical value.
