摘要
基于锚杆分担开挖荷载和提高岩体整体稳定两方面特性,借助FLAC3D数值分析软件中的cable结构单元,建立了某水电站地下厂房开挖锚杆支护模型,并用塑性耗散能指标对锚固效应进行了评价。算例结果表明采用cable单元模拟锚杆支护效应是可行的。
Based on two characteristics of sharing loads and improving the overall stability of rock mass in bolt＇s roles,cable structure elements in FLAC3D are used to build bolt-supporting models in excavation of underground powerhouse in a hydropower station;and an evaluation is made by an index called as plastic dissipated energy.The calculation result show that simulating the effect of bolt-supporting by cable element is feasible.
