带结构面围岩山岩压力计算探讨

岩体内存在着节理、断层、软弱夹层、岩层层面、片理、片麻理等各种结构面,结构面的不同组合,形成了形状不一、规模不等的各种结构体。给出了两组同倾向结构面、多组同倾向结构面、两组反倾向结构面,在不同倾角组合、不同计算条件下山岩压力的计算模式,并进行了比较分析,得出了有益的结论。

Discussion on the Pressure Calculation of Surrounding Rock with Structural Plane

There are many structural planes such as joints, faults, weak intercalations, strata planes, schistosity and gneissic schistosity in the rock mass. The different combinations of structural planes form the structural bodies of vary forma- tions and sizes. This paper gives out the calculation models and comparations to two groups and multi--groups structural planes of the same tendency and two groups structural planes of the anti--tendency. We finally obtain the profitable conclusions with different combination of dip angle and vary calculation conditions.
