Underground structures, being confined by the surrounding rock or soil, have long been assumed to have good anti-seismic ability.
地下结构由于受到周围岩体或土体的约束，一直被认为具有良好的抗震性能。

By using distribution features of stresses, displacements, and yield zones in rock mass, the stability problem of anti inclined slope is discussed.
通过含有结构面的岩体的应力，位移以及屈服区的分布特点，讨论了反倾边坡的稳定性问题。

The prestressed anchor cable is to exert prestressed tension on unstable rock mass or structure to improve anti-slide capacity and structural stress of unstable rock mass.
