Abstract: The anchored soldier pile wall as the deep excavation supporting system was used in the second contract package of the First Phase of Shimao Longwan Project in Wuhan. In order to meet the requirement of safe, cost effectiveness and construction simplification, the supporting system was optimized based on the subsurface conditions and the adjacent constrain environment. The anchored soldier pile wall was analyzed with equivalent beam method. The results indicate that the selected supporting system is adequate for the excavation. The system is satisfactorily controlled the lateral deflection, minimize the impact on the adjacent building structures and is also cost effective.

Key words: Deep Excavation, Deep Excavation in Soft Soils, Equivalent Beam Method, Anchored Soldier Pile Wall
