| Abstract: | Taking the tunnel RK2＋280- ＋300 section in a foundation pit as an example, this paper introduced a monitoring program for the pile-bracing system, and carried out some monitoring data, including the horizontal displacement and displacement at the top of the pile pit structure, surface settlement of surrounding buildings, supporting ability. Through analyzing the applicability of the strip-type support used in the deep narrow excavation, this paper pointed out that the strip-type support can guarantee safety of excavation and construction security. |
| Keywords: | foundation pit pile-bracing system displacement of settlement construction security |
