Static Analysis Model for Double Sheet‐Pile Wall Structures

Abstract

A calculation model for estimating static behavior when a double sheet‐pile wall structure is subjected to horizontal force is proposed, and a comparison is made between the results of calculations and those of model tests to examine the validity of the calculation model. The calculation model is based on the theoretical solution obtained by assuming that the portion of the structure above ground level is a composite of sheet piles and sand fill and that the portion below ground level consists of sheet piles receiving horizontal resistance from the ground, taking into consideration the elasto‐plastic characteristics of the sand fill and the subsurface soils. The calculation results show good agreement with the test results and indicate that the calculation model can be effectively used for predicting the deformation of the wall, the bending moment of the sheet pile, and the tension of the tie‐rod, which are the most important items for structural design.
