| 摘 要： | 随着全国铁路网的扩大,许多既有车站需要在维持既有线路运营的情况下进行改扩建,在这些工程中存在既有线列车荷载作用下基坑与线路之间相互影响的问题.该文以某邻近既有线施工在深基坑开挖工程为例,对此问题进行分析.根据系统动力学、有限元理论,建立铁路路基-土体-邻近线路基坑-支护结构数值计算模型,分析列车振动荷栽作用下,邻近既有...

| Abstract: | With the expansion of the national rail network,many existed rail stations have to be enlarged with-out disturbing transportation of existed lines.The most serious problem in these projects is the interaction be-tween the new excavation pit and the adjacent railway lines,especially influence of running trains on the stabili-ty of the adjacent foundation.This paper analyzes this issue based on a practical engineering project in Suzhou.By establishing the numerical model of roadbed-ground-ditch-supporting str... |
