摘要
采用大型有限差分软件FLAC3D对掌子面前方围岩加固与无加固两种情况进行了数值模拟,并对围岩和隧道结构的变形及应力进行了对比分析,得出在该围岩条件下超前加固的必要性。
This paper used huge finite difference software FLAC3D made numerical simulation to reinforcement and no reinforcement two cases ot tunnel face, and compared and analyzed the deformation and stress of surrounding rock and tunnel structure, gained the necessity of pre-consoli- dation under surrounding rock conditions.
