Study on the Treatment and Settlement Monitoring Technology of Passenger Dedicated Line Collapsible Loess Foundation

Abstract:

By the engineering background of Datong-Xian Passenger Dedicated Railway Line passing through the collapsible loess area, four representative test sections such as roadbed-bridge transition section, roadbed-culvert transition section, ordinary and special embankment section was selected. Different pile parameter and pile plane layout and subgrade filling measure has been taken according to the different test sections. At the same time, the correspondence of settlement monitoring project was carried out. After the long time monitoring, by the hyperbolic curve and logarithmic method predicting, the long-term settlement has been predicted. The monitoring results and the curve fitting shows that the settlement and the foundation treatment schemes with subgrade filling measurement meet the design requirement also provided reference and reference for other engineering.
