- 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.
