摘要
基于位移监测提出了滑坡滑动方向的判别方法,利用坐标转轴公式推导独立坐标系下测点滑动方向转化为方位角的计算公式,并依托湖南省邵坪高速公路某段右侧路堑边坡滑动治理案例,对该判别方法进行了验证。实践表明:该方法可精确地判定主滑方向,对支挡方案的确定具有重要的指导意义;斜交工程滑坡的滑动方向,一般介于坡向与岩体结构面倾向之间,边坡主滑方向更靠近于节理倾向,后缘牵引滑动区更靠近于坡向。
The discrimination method of landslide sliding direction based on displacement monitoring is proposed in this paper.The calculation formula of measuring point sliding direction converted into azimuth angle in independent coordinate system is derived by using coordinate rotation axis formula.Relying on the sliding treatment scheme of the right side cutting slopr of Shaoping Expressway in Hunan,the identification method is verified.The practice shows that:the method can accurately determine the main sliding direction,which has important guiding significance for the determination of retaining scheme;the sliding direction of oblique engineering landslide is generally between the slope aspect and the inclination of rock mass discontinuity.The main sliding direction of slope is closer to the inclination of joints,and the trailing edge traction sliding area is closer to the slope aspect.
