Numerical simulation analysis for pipe-shed and pre-grouting reinforcement of tunnel
摘要
Abstract
As two important auxiliary methods in tunnel construction , pipe - shed and pre - grouting plays a major role in preventing tunnel collapse, controlling surface subsidence and inhibiting ground displacement. Therefore, the two pre - reinforcement methods were widely used in our country. FLAC3D finite difference software was used to build four excavation models for numerical simulation analysis, including pipe - shed and pre - grouting model, only pipe - shed pre - support model, only pre - grouting support model and without any pre - support model. The effect of actions on controlling the stress, displacement and surface subsidence of tunnel are studied.关键词
