包裹式加筋土挡土墙在并行既有铁路中的应用

石家庄枢纽货运系统迁建工程新建线路局部地段与既有铁路并行不等高且线间距不足，路堤需设置支挡收坡。考虑到采用一般形式挡土墙挖基太深，影响既有铁路运营，设计采用包裹式加筋土路堤挡土墙，能很好地适应软弱地基和地基的不均匀沉降，又解决了并行既有铁路路堤放坡距离不足的问题，同时能最大限度减少对既有铁路线运营的影响。

Application of Packaged Reinforced Soil Retaining Wall for Existing Railways in Parallel

Part of the newly built line of relocation and construction of Shijiazhuang Pivotal Freight System goes with the existing railway in parallel with unequal height and insufficient spacing so that the embankment requires supporting.Considering that too deep foundation for general retaining wall may affect operation of the existing railway，packaged reinforced soil retaining wall was designed to adapt to the soft foundation and its uneven settlement，simultaneously，it offered such a solution for the issue that the distance for the embankment slope along the existing railway was not enough；and the effect on the operation of the railway could be reduced to a maximum extent.
