| 摘 要： | 本文以滑波理论为依据，总结了山西地震带的两种不同特点的滑坡。即：振荡式滑坡及触发式滑坡。虽然两种滑坡都可分为变形、解体、滑动、毁灭等四个阶段，但其动力不同。振荡式滑波的滑动面倾角小，因而滑力来源于强震振动，而触发式滑坡的滑动面倾角大，因而滑力来自滑体本身静荷载。对两种滑坡的研究对预防及减轻强震带来的次生灾害有重要的意义。

| Abstract: | This paper sums up two types of different landslides at Shanxi seismic belt, namely, commotion type and strike type on the basis of landslides theory. Although two types of landslides may be divided into four stages, namely, deformation, decomposition, sliding motion and consume, their dynamics are different, because commotion landslides angle sur-face of slip is small, therefore the force of slip is caused by the vibration of strong earthquake. As strike landslides gradient of slope surface is very big, so the force of slip comes from the dead load downslip force of sliding mass itself. Investigating on the two landslides has some significance in preventing and reducing secondary catastrophe of strong earthquake |
