文泰高速某滑坡基本特征与成因机理分析

Analysis on the Basic Characteristics and Formation Mechanism of a Landslide on Wentai Expressway

文泰高速由于施工开挖边坡前缘产生临空面,连日降水导致坡体发生变形,形成滑坡,现处于缓慢蠕动变形状态。文章通过钻探和工程地质分析,对滑坡的地形地貌、地层岩性、降水作用、人类工程活动等影响因素进行分析,查明了滑坡的基本特征,并对滑坡的稳定性进行分析,为滑坡的工程处置提供了充分依据。

Due to the formation of a free surface at the front edge of the excavation slope during construction,Wentai Expressway has experienced slope deformation due to continuous precipitation,resulting in the formation of landslides,which is now in a state of slow creep deformation.Through drilling and engineering geological analysis,this paper analyzes the influencing factors of the landslide such as topography,stratum lithology,precipitation and human engineering activities,finds out the basic characteristics of the landslide,and analyzes its stability,which provides a sufficient basis for the engineering treatment of the landslide.
