【摘要】 滑坡灾害破坏性大、治理难度高,特别是地震作用下的稳定性问题十分复杂,是土木工程界的一大难题。以小湾滑坡为研究对象,运用有限元法计算分析小湾滑坡在小震、中震、大震作用下的稳定性,得到小湾滑坡在地震作用下的稳定系数时程曲线,并以此为依据对小湾滑坡的地震稳定性进行评价,研究了小湾滑坡稳定系数与地震强度的关系。更多还原

【Abstract】 Landslides as a kind of geological disaster have great destructive power and is very difficult to control.The stability of the landslide under the seismic action is very complicated. It is a multi-discipline research issue and still a big problem for civil engineering. Taking Xiaowan landslide as research objects this paper analyzed its stability under the action of small,medium and strong earthquakes by using finite element method,then the time-histories curves of landslide stability coefficient under the influence of the earthquake was acquired. Finally,the stability of Xiaowan landslide in earthquake was analyzed combining with the data,the relationship between stability coefficient and seismic intensity was also analyzed.更多还原
