| Abstract: | The successful application of the combined retaining structure provides a new method for controlling horizontal displacement of side of foundation pit; weakening the influence on the environment; reducing the difficulty of construction of retaining structure and foundation pit; enhancing the speed of construction. In this paper, based on the comparison of merits and defects between pile-anchor and soil nailing, the development of the load carrying and deformation of the combined retaining structure during the excavating construction of foundation pit is analyzed and the distribution mode of combined retaining structure is put forward. Thus, it provides the theoretical guidance on the calculation and design method of the combined retaining structure. |
| Keywords: | soil nailing pile-anchor combined retaining distribution of earth pressure |
