缓动式低速滑坡,是自然环境和工程地质环境中一种动力类型的滑坡.它在分布、发育、危害等方面,与剧动式高速滑坡有显著差别.本文根据各类资料,在大量现场事实的基础上,按滑坡本构特性,研究概括认为,由于滑面的峰、残微差效应,滑面动静摩阻力相似效应和滑带塑性蠕变耗能效应的综合作用,滑坡启动呈现缓动性.滑体低能效应、滑体低推力效应、滑带(面)强度自行恢复效应和滑体自行消能效应的叠加作用,导致滑坡以低速运移.
The slow-moving low-speed landslide is a dynamic type of landslide in the natural environment and engineering geological environment, which has significant differences with the high-speed landslide in the aspects of distribution, development and damage, etc. Based on all kinds of data, Based on the facts, based on the constitutive characteristics of landslide, the research concluded that due to the combined effect of slippery surface peak, residual difference effect, sliding surface static and dynamic friction resistance effect and sliding plastic creep energy dissipation effect, The low energy effect of the slide body, the low thrust effect of the slide body, the self-recovery effect of the strength of the slide belt (surface) and the self-energy dissipation effect of the slide body lead to the low-speed landslide migration.
