| Abstract:Based on the typical deep foundation pit bracing project in soft soil in Wuxi, the application of secondary grouting soil nailed wall for deep foundation pit bracing and construction control were introduced. The bearing capacity of secondary grouting soil nail and settlement & displacement of bracing structure during construction were summed up to analyze and evaluate the economic with the special experiments and monitoring results. It shows that the secondary grouting soil nailed wall is an economical, fast and safe bracing method which can greatly increase the bearing capacity and has no unfavorable influences on the bracing structures. |
