Abstract

Research purposes:To ensure high-speed train running safety,the control requirement of settlement after construction of the ballastless subgrade is very strict. The abnormal deformation is found in a station of a passenger dedicated line,and the maximum horizontal displacement is nearly 80 mm which is much higher than the norm allowable value and seriously affects the safe operation of high-speed trains. So the reasonable measures must be taken to renovate the horizontal section subgrade deformation exception paragraph.
Research conclusions:The treatment technique of abnormal deformation is very success. The conclusions are as follows: (1)It is feasible to control the lateral deformation of subgrade with high pressure jet grouting pile. The lateral thrust generated by the construction can be carried out slowly and effectively.(2)The monitoring system,which contains leveling,track monitoring car, deep soil layer displacement monitoring and pore water pressure monitoring,has been adopted to ensure the construction safety.(3)The early warning and forecasting procedure and management system are established,which ensure the implementation of the remediation technique.(4)This research provides a useful reference for the disease treatment of high-speed railway subgrade deformation.
