FLAC3D在岩质边坡稳定性分析及防护效果评价中的应用

摘要

Combinning with example of rock slope excavation and protection in YK52+408~YK52+588 section of Sansui to Liping highway LJ16 section, this paper will simulate the slope excavation and protection construction process using FLAC3D, and through the simulation process analysis, reveal overall stability and deformation development process of the slope. Through comparison of stress diagram, displacement diagram and relevant data of the slope before and after protection, it will make an evaluation to the slope stability and protection effect, and provide the basis for the rational protective structure.%结合三黎高速LJ16标YK52+408~YK52+588段岩质顺层高边坡开挖防护实例，采用FLAC3D模拟边坡开挖和防护施工过程，并通过对模拟过程的分析，揭示坡体的整体稳定性及坡体变形发展的过程。通过对防护前后边坡应力图、位移图及相关数据的比较，对边坡的稳定性及防护后效果作出评价，为采用合理的防护结构提供依据。
