摘要
Abstract
Based on the third phase of the Shijiazhuang Metro Line 1 project,which passes underneath the Huachai culvert of the mainline of the Middle Route of the South-to-North Water Diversion Project,a three-dimensional finite element simulation model was established according to the actual structural design and geological conditions of the site.The analysis showed that during the shield tunneling process,the vertical deformation was reduced by 0.74 mm,and the maximum differential settlement between pipe segments was reduced by 0.4 mm when deep-hole grouting reinforcement measures were applied,compared to scenarios without such measures.Based on the maximum deformation,the bearing capacity and reinforcement of the Huachai culvert were re-evaluated,and both were found to meet the requirements.With the implementation of reinforcement measures,the settlement of the culvert could be controlled within 5 mm.关键词
