土压平衡盾构下穿铁路沉降影响分析

Analysis of influence of earth pressure balance shield on railway settlement

盾构施工下穿铁路引起线路变形,对铁路安全运营产生严重影响。以盾构下穿胶济铁路为研究背景,通过数值模拟分析和理论计算对盾构下穿胶济铁路引起的沉降变形规律进行了研究分析,为后续施工提供了参考。

The shield construction under the railway causes deformation of the line,which has a serious impact on the railway safety operation.Taking the shield tunnel under the Jiaoji railway as the research background,the numerical simulation analysis and theoretical calculation are carried out to study the settlement deformation law caused by the shield under the Jiaoji railway,which provides a reference for the subsequent construction.
