Irrigation is essential to the agricultural basis of the loess region economy;however,it has resulted in lots of loess landslides in recent years.
黄土滑坡一个普遍特征就是后缘发育地裂缝以及落水洞,使地表水(灌溉水以及降雨)直接灌入坡体,诱发了大量黄土滑坡。
To study the cause of these landslides,the physical,mechanical and dynamic characteristic properties of the loess in the area were studied to reveal the relation between loess landslides and its soil mechanical properties.
8级地震,触发了150多处滑坡,为了分析地震区黄土滑坡灾害的成因,通过对地震滑坡区域内黄土的基本物理力学性质和动力特性的试验,研究了黄土的相关性质与易损性关系,并对地震引起黄土滑坡的原因进行了探讨。
