软土地区盾构侧穿铁路箱涵影响分析

The influence analysis on shield side crossing railway box culvert in soft soil area

针对某地铁工程盾构区间绕避侧穿铁路箱涵,下穿铁路路基的工程情况,建立了整体有限元模型,分析了穿越工程对铁路路基及铁路箱涵的影响,并提出了应对措施,从而保证铁路运营和施工的安全性。

According to the engineering situation of shield section avoidance routing side crossing railway box culvert of a subway engineering, underpass railway sub-grade, this paper established the overall finite element model, analyzed the influence of crossing engineering to railway sub-grade and railway culvert, and put forward corresponding measures, so as to ensure the safety of railway construction and operation.
