摘要
地基边坡大规模的开挖造成地应力在一定程度上的复活，从而形成岩层或岩体的剪切错位，外观表现为地基边坡炮孔和大口径钻孔的剪切错位。由此建立了地应力动态平衡论。以此错位量，可以反演该区的地应力数值。地应力可以集中，也可以传递和扩散，“边坡作用地应力”对边坡稳定有一定的影响。
The dislocation of rockmass is formed and appears as the shear dislocation of explosive hole or borehole with large diameter as the foundation slope is excavated and the in situ stresses are reacted to some extent. The dynamic equilibrium theory of in situ stresses is established. The in situ stresses can be back determined with the dislocation in given area. The in situ stresses can be concentrated, transmitted, and spread, which affects the stability of slope.
