地壳中岩石的变形模式受构造应力、流体压力和上覆岩层重力共同作用的影响。
Deformation pattern of rocks in earth's crust is effected by tectonic stress, fluid pressure and gravity of the overlying strata.
结果表明：显德汪煤矿垂直应力近似等于上覆岩层的自重应力，最大主应力为北东方向，且为近水平压应力。
The results show that vertical stress is equal to overburden stress at shallow level. Maximum principal stress is sub horizontal stress in the NE direction.
室内相似材料模拟试验结果显示了底板岩层竖直应力分布规律及采空区上覆岩层破坏形式。
The results of the simulation model experiment showed the vertical stress distribution of the bottom board rock and the failure form of...
