The problems in the free and fixed earth support methods for thd design of the anchored sheet pile wall for excavation are briefly discussed. A new method for the design is proposed. A forces equilibrium rather than moment equilibrium method is adopted to calculate the length from the point where the stress of the soil down to zero to the bottom of the pile. The calculation is simplified by the new method, and the results approach to the goal of safety and cost saving. The details of the calculation procedures and examples to demonstrate the calculation are presented in this paper.
