考虑地下水作用的 Goodman-Bray 方法改进及应用
Improved Goodman-Bray Method in Consideration of Groundwater Effect
摘要
Abstract
Goodman-Bray Method is commonly used in the stability analysis for toppling rock slope,but the effect of groundwater is not considered.In view of this,we made an improvement to the Goodman-Bray method by deducing the stability calculation of toppling rock slope in consideration of groundwater effect,and wrote calculation program by using MATLAB.With a toppling rock slope in Wuxi,Chongqing City as a case study,we verified this improved Goodman-Bray method using Sarma Method and Transferring Coefficient Method (TCM)for comparison.Results suggest that the improved Goodman-Bray method and Sarma Method which combines rock block and structural planes could better reflect the practical situation than TCMbecause of the limits of toppling rock mass.But the con-nectivity of block bottom is neglected by using Sarma Method so that the calculation result is smaller than practice. So this improved Goodman-Bray method is more suitable to be used for stability analysis of toppling rock slope in consideration of groundwater effect.关键词
