铜鼓县城郊林场滑坡特征及稳定性分析

铜鼓县城郊林场滑坡是一个较典型的堆积体滑坡,滑坡位于陡坡上,公路切坡破坏了自然斜坡结构与力学平衡,在暴雨作用下诱发。滑坡前后缘变形活动特征明显,造成多栋房屋受损,且危及到下游县城安全,引起了省市领导高度重视,成为全省少有的几个专业监测点之一。本文分析了滑坡变形特征和形成机理,并对滑坡稳定性进行了计算分析,在此基础上提出了滑坡治理和监测措施。

Analysis of the Characteristics and Stability of the Landslide in Forest Farms of Tonggu County Suburb

The landslide of Tonggu County forest farm, located on steep slopes, is a rather typical talus landslide. The highway cut slope destroys the balance between the structure and mechanics of the natural slope, which can easily evoke landslide under rainstorm conditions. Changes of the landslide＇s front and back edges are obvious, making many houses damaged and endangering the safety of the downstream county, which attracts the attention of the Provincial and Municipal leaders. The county becomes one of the few professional monitoring points in Jiangxi Province. This article analyzes the landslide deformation characteristics and formation mechanism, and also calcu- lates and analyzes the landslide stability. On the basis of the former part, it proposes some landslide control and monitoring measures.
