Stability Analysis of Sheet Pile Walls by Discontinuity Topology Optimization

A kinematic approach based on the framework of limit analysis is applied for stability analysis of sheet pile walls. A rotational failure mechanism is used to computer safety of factor, and the topology optimization technique is employed in the stability analysis. The analyses generally yielded good accord with the results in many aspects of the sheet pile walls behavior. The novel implementation of upper bound method with discontinuity topology optimization is reliable and useful for engineering practice and design.
