摘要

通过对常用滑坡滑速计算公式推导过程及其使用条件的分析,阐明了常用的计算公式不能适用于暴雨和地震触发型平缓滑坡的滑速计算。同时,根据这类滑坡产生的力学机制,抓住其主导因素,对平推式滑坡采用能量守恒和动量守恒定理推导出滑速计算公式,对地震触发型滑坡还推导出考虑地震作用的等效摩擦系数。
With analysis of both the deducing and the application of computing formula for landsliding velocity,which is common used,the common formula is not suitable to applied to the mechanism of landslide triggered by rainstorm and earthquake.The paper modified the formal formula and deduced the new one for this kind landslide with level gliding landslide based on Conversation of energy.On the other hand,the velocity formula of landslide earthquake triggered is also achieved to the equivalent coefficient of the slip-surface friction.
