隧洞临近敏感建筑物的变形控制措施分析
Analysis of Deformation Control Measures for Tunnels Adjacent to Sensitive Buildings
摘要
Abstract
In response to the safety control challenges of hydraulic shield tunnels crossing railways,this paper uses numerical simulation to study the reinforcement effect of drilling and grouting isolation piles combined with grouting,based on a case study in Fujian province.The results showed that without reinforcement,shield tunneling construction resulted in a maximum settlement of 10.8 mm for the roadbed and a maximum horizontal displacement of 7.6 mm for the bridge piers,both exceeding safety standards.After adopting the reinforcement schemes of"drilled pile+crown beam support"and"sleeve valve pipe grouting"for the bridge foundation and subgrade respectively,the settlement of the subgrade and the displacement of the bridge piers were reduced to 3.6 mm and 1.9 mm,respectively.The internal forces of the structure met the safety requirements and the deformation could be effectively controlled.关键词
