Abstract: The soil nailing walls is a kind of retaining structure to stabilize foundation pit and slope. Composite soil nailing walls is formed by combining soil nailing with prestressed anchor bar. According to the interactive mechanism of soil nailing, prestressed anchor bar and soil mass, a jointly interactive model is proposed to simulate supporting and anchoring effect of the composite soil nailing walls. The mechanical model is applied to a deep & large foundation pit which was designed by authors; and the supporting design scheme for the foundation pit has been effectively optimized. Stability of the foundation pit and safety of surrounding environment under excavation state have also been ensured. The supporting for foundation pit has achieved complete success.

Key words: composite soil nailing walls, jointly interactive model for soil nailing and prestressed anchor and soil mass, deep &, large foundation pit, stability of foundation pit under excavation state, safety of surrounding environment
