基于数值计算的边坡位移监测点优化布设方法研究

Study on Setting of Slope Displacement Monitoring Points by Numerical Calculation

边坡位移监测能够直观的反映边坡的变形情况，而监测点的合理布设是取得良好监测效果的前提。目前，边坡位移监测点位的布设大多依靠经验以及工程类比方法，缺乏定量的分析。根据有限差分强度折减法，得到拟布监测点随强度折减系数变化而变化的位移情况，分析拟布点位移与折减系数的变化规律，得到二者的灰色关联度，提出了根据灰色关联度大小并结合实际工况优化布设监测点的方法，可以为边坡位移监测点优化布设提供理论指导。

Slope displacement monitoring can visually reflect the slope deformation, and reasonable setting of monitoring points is the premise for good monitoring results. At present, the slope displacement monitoring site mostly rely on the experience and the engineering analogous method, which are lack of quantitative analysis. According to the finite difference strength reduction method, get the displacement of distributed monitoring point with the changing of strength reduction coefficient, analyse the rule between the displacement of distributed monitoring point and reduction coefficient, and obtain the grey pertinence between them. Give the idea that optimizing the monitoring points based on gray correlation degree and actual condition.
