Abstract:

The design and construction risk are very important to foundation pit supporting of metro transfer station. Hence, the characteristics of foundation pit of metro transfer station are analyzed, the plane outline of first floor of foundation pit is optimized, and the circular ring frame beam supporting system is adopted. The system adopted is characterized by easy control, low dismantling risk, simple construction sequence, etc. The system is applied to Tianhe Park Station on Guangzhou Metro No. 21 and Cultural Park Station on Nantong Metro to verify its practicability. The results can provide reference for similar projects in the future.

Key words: foundation pit of metro transfer station, circular ring frame beam support, retaining structure, key technology
