Corrugated Sheet Pile Analysis on Riverbank Retaining Wall Project in Factory Area of the Sukoraharjo Street

Abstract

This retaining wall projects serves to hold the land close to the riverbank in the factory area of Sukoraharjo street, Malang. The height of the riverbank starting from the bottom of the river to the upper edge is around 7 m. The shape of sheet pile is determined using corrugated sheet pile. Calculation method using Plaxis 2D software. The stages of modeling in 2D Plaxis starts from determine the geometry of the soil profile and sheet pile. Then determine the input parameters of soil and sheet pile. After that determine the generate mesh opsi in the initial or existing geometry and conditions. After the procedure the calculation is done with the phases that have been determined. From the results of Plaxis 2D modeling and stability and strength analysis, that corrugated sheet pile type W - 500 Class B with a permanent permit moment of 299 kN m can be used as a retaining wall for riverbank with a height of 7 m in the factory area of Sukoraharjo street, Malang.. The depth of the corrugated sheet pile is embedded as deep as 7 m so that the total length of the sheet pile is 14 m. The safety factor value of the corrugated sheet pile stability is 2.98. This value is in accordance with the requirements of SNI 8460 - 2017.
