摘要
以太原二环高速公路凌井店至龙白段(东二环)为依托,基于FLAC有限差分法,对边坡开挖过程中水平、竖向位移及塑性区发展情况进行模拟分析,利用极限平衡法计算开挖过程中边坡安全系数。根据计算结果给出边坡处治方案,为类似高速公路边坡设计提供参考。
Based on the Lingjingdian-Longbai section (East Second Ring Road) of Taiyuan Second Ring Road and FLAC finite difference method, the simulation analysis on the development of horizontal and vertical displacement and plastic zone during the slope excavation is made, and the safety factor of slope during the excavation is calculated by limit equilibrium method. According to the calculation results, the slope treatment scheme is given, which can provide reference for similar expressway slope design.
