This paper presents the method of iteration and accumulation for braced sheeting pile wall in deep excavation engineering, which be suited to heterogeneous stratumstratified soil. The series of formulae and condition for iteration and accumulation have been given to benefit of computation in programming design or others. According this method and result of computation, it can be selected and optimized in deep excavation engeering.
Keywords: iteration method; deep excavation engeering; braced sheeting pile wall
