Abstract

To understand the internal force and deformation generation mechanism of the double-row steel sheet pile cofferdam in complex stress conditions and determine the most unfavorable working condition, this paper adopted the finite element method to analyze the displacement, axial force of steel tie bars and bending moments of steel sheet piles in various construction stages at different water levels and under different load types. The study shows that the deformation and internal force of the cofferdam are affected by the water level, fill light weight, vertical construction load, horizontal wave load, and wind load. The most unfavorable conditions for displacement and steel tie bars are the high water level-horizontal load and the low water level-vertical load respectively, while the most unfavorable condition for steel sheet piles needs to consider a variety of conditions to take the maximum value.
