shear strength of rock

During the deformation, disintegration and failure of debris-soil landslides, in space the plastic strain of the sliding mass and shear strength of the rock or soil mass on a sliding plane are different.

在碎石土滑坡变形解体破坏过程中，在空间上滑体塑性应变和滑面上岩土体抗剪强度的发挥程度是不一致的；

Tectonic effects, when the rock in the fractured reservoir water in the atmosphere or rain soaked, under the influence of fluctuations, the shear strength of fissure filling material dramatically reduced, rock will be unstable. 2.

地质构造影响，当岩体中的节理裂隙在大气降雨或者库水浸泡、涨落的影响下，裂隙充填物的抗剪强度急剧降低，岩体将失稳。

At the extent of 55 °≤δ≤ 70 °, maximum shear stress of closer empty element rock mass is all less than compressive strength of coal bed roof and floor plate mudstone including shale interlayer.

在55°≤δ≤70°范围内，煤层开采临空单元岩体最大剪应力皆小于煤层顶、底板泥岩夹页岩的抗压强度，其屈服接近度也大多小于10。
