| Abstract: | Cut-and-cover method is often used in the construction of metro tunnel in Tianjin, where the underground continuous wall is usually used when the cement treated column as the waterproof curtain is not applicable because of the complicated geological conditions. This leads to the drilling occlusive pile as a retaining structure being firstly used in the reconstruction engineering project of Tianjin metro. A field observation and an evaluation analysis are described in detail in this paper. It will be widely used in the metro construction. |
