| Abstract: | Based on the monitoring data of 28 sections of 2 work sites on Wuhan-Guangzhou High-speed Railway,the deformation characteristic of CFG pile composite foundation under embankment load was analyzed.The settlement correction coefficient was obtained by using the layering summation method,so it was use to calculate the settlement of CFG pile composite foundation under embankment load,which could provide a useful reference for the similar engineering. |
