Optimization Layout of Slope Displacement Monitoring Points Based on Numerical Computation

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 sites mostly rely on the experience and the engineering analogous method, which are lack of quantitative analysis. The displacement of quasi monitoring point with the changing of strength reduction coefficient, including analyzing the rule between the displacement of quasi monitoring point and reduction coefficient, are studied by using the finite-difference strength-reduction method, which gets the grey pertinence between them and achieves the idea that optimizes monitoring points based on gray correlation degree and actual condition. It may provide theoretical guidance for the optimization layout of slope displacement monitoring points.
