Discussion and Analysis about the Particularity of Pebble Stratum and Its In uence on the Selection of Foundation Pit Supporting Structure and Construction Technology |
| |
| Abstract: | The selection of foundation pit supporting structure and construction technology are in-depth and systematic analyzed in this paper from the three aspects: the pebble stratum feature classi cation, special structure and eld construction conditions. The aim is to make the design of foundation pit bracing be more scienti c, economic, and the construction method and technology be more maneuverability. |
