Abstract:An embankment settlement monitoring technical scheme was developed for purpose of embankment settlement monitoring in operation and maintenance of express railway based on the features of high flatness of high-speed railway and routine maintenance and regulation works below embankment line. Monitoring sections were arranged and stable points CPIII on bridge were selected as reference points for embankment settlement monitoring and the observational method was used by taking CPIII points in monitored route as turning points. This technical scheme solves the problems of difficult fixation of monitoring points in surface settlement zone and tight schedule for maintenance and monitoring works and its application in embankment settlement monitoring during maintenance and operation stages generated positive results and meet technical requirement for third-level deformation measuring of high-speed railway.
