Abstract
This paper presents a parametric study of the stability of cantilever sheet pile walls in clays by using the plane strain finite element analysis. In the finite element analysis, the cantilever sheet pile wall is modeled by using plate elements while the clay is modeled by using volume elements and obeys the Tresca failure criterion. The cantilever sheet pile wall has the excavated height and the embedded length. The clay has the unit weight and the undrained shear strength. By using the strength reduction method, the safety factor of the cantilever sheet pile wall at the limit state can be obtained. The results presented in the paper are illustrated in the form of design charts of dimensionless parameters, which are the relationships between the stability factor and the wall embedded length ratio. The proposed design charts of the stability factors can be employed to preliminarily estimate the embedment of the cantilever sheet pile walls that are widely constructed in practice.
