基于折减系数的全风化花岗岩边坡稳定性评价
Evaluation of Completely Weathered Granite Slope Stability Based on Reduction Coefficient
摘要
Abstract
The physical and mechanical parameters of rock and soil were obtained from two typical disease slopes of fully weathered granite selected in a highway through in-situ test and indoor test.The average reduction coefficient was calculated,and the slope stability simulation was carried out.The classification method of stability evaluation and the focus of slope maintenance were put forward.The result shows that,the fully weathered granite slope collapse is still one of the main diseases in the operation period;the simulation calculation parameters should be based on the field test,because the indoor test value is a little small.Based on the method of reducing geotechnical parameters,the slope stability of the study section can be divided into Ⅰ,Ⅱ,Ⅲ and Ⅳ categories.The slope stability is closely related to the thickness of fully weathered granite,slope rate and wide platform.Class Ⅰ slope should focus on daily maintenance.Class Ⅱ slope should rely on the development of slope deformation and slope toe seepage.Class Ⅲ slope should be monitored for stability.If obvious signs of deformation are found,special survey and design of slope should be carried out in time.Class Ⅳ slope should have special assessment,survey and design of slope conducted.关键词
