基于FLAC3D的复杂堆积体稳定性分析及其治理研究
Stability analysis and treatment of complex accumulation body based on FLAC3D
摘要
Abstract
For complex accumulations with unfavorable structures distributed in three-dimensional space and multiple strata distribution,it is difficult to simplify them into a simple abstract model for theoretical calculation.In order to solve the stability problem of complex accumulations,using FLAC3D software to build 3D geological models,according to the engineering characteristics of the accumulation body of the BaiLong Bridge on the Duyun—Anshun Expressway in Guizhou,partition assignment,joint calculation,the deformation and failure mechanism and stability of complex accumulation body were analyzed.The results show that,this method can di-rectly simulate the deformation and failure characteristics of the accumulation body.The numerical simulation results show that the large displacement area of the landslide is distributed in Zone 2 and Zone 3,and the land-slide of the accumulation body pulls back from Zone 2 to Zone 1,forming a whole slip.The proposed route se-lection scheme of"route local circumvention+engineering support"is more effective,reasonable and economi-cal.The research results can provide reference for stability analysis of complex accumulation body and the formu-lation of treatment scheme.关键词
