(1.Shanghai Jianfeng Vocational College Shanghai 201900 China;2.Shanghai Foundation Engineering Group Co. Lad.Shanghai 200002 China) Abstract:Due to its constructional feasibility waterproof ability and repetitive usage possibilities steel sheet pile cofferdam has been widely used in a variety of permanent and temporary construction works including ports docks river bank protection retaining walls underground structure bridge bearing platform cofferdam and other projects.Based on the single-layer steel sheet pile cofferdam used for construction of a bridge pile at a depth of nearly 10m of the river this paper establishes 3D mechanical model with software MIDAS /Civil calculates the strength and inflexibility of steel sheet pile and checks the realistic load-carrying capability and stability of supporting structure to ensure its accuracy and safety which helps to meet the needs of cost control construction period deduction a...
