摘要:
高速铁路对变形要求严格,针对某高速铁路车站路基沉降异常,通过设计及施工质量核查﹑区域构造引起的路基沉降、地下水开采引起的路基沉降及周边建筑物基坑抽水引起的路基沉降分析,准确查明站前广场基坑工程降水是引起本段发生路基地面沉降的原因,分析并确定基坑抽水影响范围.据此采取针对性的处理措施,通过对线路纵断面拟合调整满足轨道的平顺性,随即停止站前广场基坑降水，控制和限制基坑后续施工抽水,监测显示路基沉降得到快速控制,保障了高速铁路的安全平稳运营．
Abstract:
High speed railway is strict with the requirements for deformation,for the subgrade abnormal settle-ment on one high-speed railway station,through the verification of design and construction quality and the analy-sis of subgrade settlement caused by the regional structure and the exploitation of groundwater,and the founda-tion pit dewatering of surounding buildings,it has been found out that the reason which has caused the the sub-grade foundation settlement is the foundation pit dewatering of station square,the influence scope of foundationpit pumping has been analysized and determined. Therefore,the efficient solution has been adopted,Thesmoothness of track has been satisfied by fitting and adjusting the vertical section of railway line,the foundationpit dewatering of station square has been immediately called of,the foundation pit dewatering of subsequentconstruction has been controlled and limited,monitoring has shown that the subgrade settlement of has been con-trolled rapidly and effectively,it has been ensured that high speed railway operates safely and stablely.
