| 摘 要： | 山区道路沿线的人工边坡很多。强震时,这些边坡经常会出现严重的破坏,除直接造成的损失而外,还会断绝交通给防震、抗震救灾带来极大的困难。本文通过云南通海、昭通、辽宁海城等地震区、公路和铁路的人工岩质路堑边坡的宏观震害资料,试图对此类边坡的抗地震稳定性及其受震破坏的规律性进行分析以探求震区岩质边坡稳定条件,为设计此类的边坡提供必要的依据。

| Abstract: | The failure of artificial rock slope of cut in macroseismic area always causes enormous damage. From the data of various macroscopic earthquake damages in Tonghai, Zhaotong earthquake areas (Yunnan Provirice) and Haicheng earthquake area (Liaoning Province) and from the point of view of engineering seismogeology, the structure of rock mass, the spatial combinatory relationship between the structure surface of rock mass and the slope orientation, and the effect of seismic intensity on the stability of the slope of cut are discussed in this paper. In addition, some ideas with practical engineering significance are presented for reference. |
