摘要： 重庆市某井场滑坡位于低山山顶部，暴雨情况下其南侧发生了滑坡变形，出现挡墙变形、围墙开裂、地面塌陷等情况，不但影响天然气开采，更为场区的施工、人员安全埋下隐患，从而造成巨大损失。从边坡的地质环境条件和岩土体特性出发，采用二维有限元数值模拟方法，对边坡的稳定进行了分析评价。

Abstract: The gas well site in Chongqing is located at the top of a rolling hill.  A landslide occurred after several heavy rains since 2011. Within the landslide affected area, the deflection at the retaining walls, cracks on the vertical fence walls, and subsidence on the ground surface are observed. The landslide is a very common geohazard in the region. The slope instability hazard will not only adversely affect the gas extraction, but also infers a potential safety concerns for the site personnel and construction and even causes a huge loss of both property and human life.This paper presents the twodimensional finite element method applied in the slope stability evaluation based on the characteristics of the geological and subsurface conditions of the site.
