一种改进的空间相关系数在水库高边坡外观变形监测中的应用
Application of an Improved Spatial Correlation Coefficient toExterior Deformation Monitoring of High Slope in Reservoir Area
摘要
Abstract
Conventional monitoring of reservoir slope is mainly focused on the deformation and stress changes of single point rather than the overall deformation with multiple points.In view of this, an improved spatial correlation coefficient is proposed to calculate the spatial correlations among multiple points of slope.The present coefficient is based on Pearson''s correlation coefficient and Moran''s correlation coefficient, and takes the spatial coordinates of different measuring points into consideration.Three relevance indexes of exterior deformation of slope are proposed, namely relevance degree Rij of measuring point, influence degree Ii of measuring point, and integrity degree I of slope.The overall state of slope can be obtained according to the variation trends of the indexes.The present coefficient is applied to analyzing the deformation data of the high slope of a concrete dam, and the results prove that the coefficient presented in this paper is practical and rational for analyzing the safety of slopes.关键词
