| 摘 要： | 以某高速公路下穿既有铁路的基坑工程降水设计为背景，运用“大井法”进行基坑降水设计，初步拟定了该工程降水方案。运用MIDAS软件对分析计算不同降水方案在不同时刻对铁路路基的影响，并建立相应的影响曲线进行分析，同时拟定现场实际降水方案，现场实测量与模拟量对比分析从而优化降水方案。

| Abstract: | With dewatering design of highway underpassingexisting railway foundation excavation engineering, theyuse Great Well Method to design the foundation excavation and draw up an initial dewatering scheme. Using Midas software to analysis different dewatering schemefor the impact of the railway embankment in different time, and the estab- lishment of the corresponding curve to analysis, at the same time propose practical dewatering scheme, analysis the actual measurement and simulation in order to optimize dewatering scheme. |
