Research on Optimization of Arch Method and Safety Control Technology of Shallow Buried Large-span Subway Station in Complex Environment
摘要
Abstract
The complex engineering geological conditions of the city seriously threaten the safety of the construction of the underground excavation method of the shallow buried large-span broken stratum station,and the influence of the underground excavation construction on the surrounding rock and the underground pipeline has not been studied for reference.In order to optimize the construction scheme and provide engineering experience,based on the project of Jiangshuiquan Road Station of Jinan Metro Line 4,this paper carried out excavation model tests of various excavation methods for shallow-buried large-span subway stations in complex environments.According to the mechanical behavior of different excavation methods in the construction process,the double-layer superimposed primary arch cover method and related construction parameters are optimized.Finally,the stress,deformation and settlement laws of surrounding rock and underground pipeline after excavation by double-layer superimposed primary arch cover method are analyzed,and the rationality and accuracy of the construction method and parameter optimization analysis are verified.关键词
