Laboratorium Experimental Of Cantilever Sheet Pile Behaviour On Soft Soil Induced By Strip Load

Abstract

This study aims to analyze the deflection behavior of the sheet pile through experimental testing and numerical analysis using the Finite Element Method (FEM). The Laboratorium scale test on a Tub with length of 1500 mm, width of 600 mm, and height of 1500 mm, and Steel Plate 3.2 mm with dimensions of 1400 mm x 590 mm was used as a model of the sheet pile wall. The subgrade material is clay soil and embankment material in the form of Sirtu which passes the No. sieve. 40. Physical and mechanical testing of soil and gravel materials is carried out with reference to ASTM standards. The measurement of the value of the strip load (q) and deflection was carried out using a load cell with a capacity of 100 kN and a linear variable differential transformer (LVDT). The deflection of the sheet pile was using was analyzed using Plaxis 8.2 software of the FEM method. The results of laboratory tests show that the pile wall collapses at a load of 74 kN/m2, with a deflection of 24.56 mm, while the FEM analysis shows that the pile wall collapses at a load of 71 kN/m2 with a deflection of 21.29 mm.

The influence of distant surcharge load with a finite length on the cantilever walls

“…Using three-dimensional FE models, Zhang and Sun [ 35 ] investigated the response of piles close to surcharge loads. Rauf et al [ 36 ] presented the deflection of the sheet pile owing to surcharge load on backfill utilizing experimental investigation and numerical analysis using FEM -based software. The stability and behavior of the rigid cantilever retaining wall that supports dry sandy soil were investigated by Al-khafaji et al [ 37 ] regarding the location of the surcharge load using a 2D finite element model.…”
