三江连通工程软土地层中盾构隧洞地震响应分析与注浆加固效果研究
Study on the Seismic Response Analysis and Grouting Reinforcement Effect of Shield Tunnel in Soft Soil Stratum of Three River Connection Project
摘要
Abstract
Based on the follow-up optimization project of Hanjiang-Rongjiang-Lianjiang River water system connection,the problem of seismic safety and seismic reinforcement of shield tunnel in soft soil stratum was addressed.In this paper,the numerical simulation method was used to analyze the seismic responses of the shield tunnel and the in-tunnel grouting reinforcement scheme was studied.The numerical simulation results showed that grouting reinforcement can effectively reduce the seismic responses of the tunnel.With the increase of grouting reinforcement angle,reinforcement depth and elastic modulus of the reinforced soil,the seismic response of the tunnel decreases.Based on the results of numerical simulation,the proposed grouting reinforcement scheme for the selected section was given,that is,the reinforcement angle is 120 °,the reinforcement depth is 3 meters,and the elastic modulus of the reinforced solid is 300MPa.According to the proposed reinforcement scheme,self-compacting motar was prepared and field grouting test was carried out.关键词
