使用Midas/GTS有限元软件对高栏港高速公路K47＋700～K59＋201.631段软基施工,并对周边土体位移进行了数值模拟分析。根据不同供水管接头对变形适应能力的不同,分析与路线平行的供水管,在软基采用排水固结法施工时允许变形,并在此基础上对高栏港高速公路扩建施工中沿线管线的保护、拆迁提出合理建议。%The paper adopts Midas/GTS finite element software to undertake the numeric simulation analysis of the surrounding soil displacement of K47＋700~K59＋201.631 along Gao-Lan-Gang Expressway,analyzes the water-supply pipe which is parallel with the road according to the fact that different water-supply pipe connectors have various adaptabilities for deformation,indicates the deformation is allowed by adopting the drainage consolidation method on soft foundation,and points out some reasonable suggestions for the protection of the pipeline along the road and the removal in the enlarging construction of Gao-Lan-Gang Expressway based on the previous points.
