滑坡监测目前主要采用三维位移监测的方法。监测点的布置依靠经验来选择,不能准确而全面地反映滑坡的运动情况。为克服这些不足,本文引入一种新的确定监测点的方法—有限差分法。在介绍有限差分法基本原理的基础上,结合具体的滑坡防治工程,建立起计算模型,并将实测位移值与计算位移值进行对比分析。可以看出,计算位移值与实际监测的位移值相差很小,说明该方法能够较为准确地预测滑坡变形情况,因而可以用于选定滑坡监测点。
Landslide monitoring is mainly used three-dimensional displacement monitoring method. The arrangement of monitoring points depends on experience and can not accurately and fully reflect the landslide movement. To overcome these shortcomings, this paper introduces a new method to determine the monitoring points - finite difference method. Based on the introduction of the basic principle of the finite difference method and the concrete landslide prevention and control project, a calculation model is established, and the measured displacement value is compared with the calculated displacement value. It can be seen that the difference between calculated displacement value and actual monitored displacement value shows that this method can predict the deformation of landslide more accurately and thus can be used to select landslide monitoring points.
