英文摘要	Research purposes: The settlement of back fill behind abutment is the main cause for the differential settlement and the vehicle bumping at bridge-head. To explore the post-construction settlement of bridge-subgrade transition section under self weight and vehicle load, in-situ monitoring of subgrade settlement is carried out on the Lanyon highway. Settlement cells are embedded in various depths of the driveway and the shoulder of highway. Long-term settlement monitoring is conducted to investigate the variation of settlement with time and space, to provide a basic data for future research on bridge-subgrade transition section in highway construction. Research conclusions: (1) The settlement of highway shoulder is greater than that of the driveway; (2) The settlement of subgrade will increase with time, while the settlement of bridge-subgrade transition section tends to be stable after one year; (3) The vehicle load has insignificant effect on the subgrade settlement; (4) Logarithm models can predict the post-construction settlement of the subgrade accurately; (5) This research achievements can provide the reference for the design and construction of bridge-subgrade transition section. © 2017, Editorial Department of Journal of Railway Engineering Society.
