Improved Goodman-Bray Method in Consideration of Groundwater Effect
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 TCM because of the limits of toppling rock mass. But the connectivity 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.
