Influence of Strip Load on Seismic Behavior of Cantilever Sheet Pile Walls
Publication: Geo-Congress 2023
ABSTRACT
Cantilever sheet pile walls are generally used to retain the moderate height of excavation in both cohesive as well as cohesionless soil as a temporary or permanent structure. These structures are highly vulnerable to seismic conditions due to the non-availability of suitable anchors or mass to strengthen them. In practice, a surcharge in the form of a strip load of finite width is generally present on the backfill. Therefore, in the present study, cantilever sheet pile walls having strip load on the backfill are analyzed using an explicit finite difference-based computer program FLAC2D. A parametric study is done by varying the seismic acceleration coefficients, excavation height, width, and distance of the strip load from the cantilever sheet pile wall. The results show that a strip load of width 2–3 m (among chosen widths) placed on the backfill gives the maximum bending moment in the cantilever sheet pile wall.
