Numerical Study of Sheet Pile Walls to Facilitate Rural Construction
J. Environ. Nanotechnol., Volume 6, No 2 (2017) pp. 115-121
Abstract
Many rural structures require initial protection of construction area from waterbodieslike construction of;embankmentsto hold flood water,civil facilities near lakes or ponds, and culverts passing from catchment areas etc.Sheet pile walls is the well-known temporary structure used to facilitate the construction of water front structures in different water bodies like ponds, lakes and rivers etc. This paper is intended to formulate a simple method to study Influences of ground water variation, embedment depth and type of soil on the pressure distribution and maximum bending moment in a sheet pile wall.Depth of embedment below dredge level was first determined from commonly used classical method. Later on, Location of maximum bending moment, allowable lateral displacement and stress distribution etc were obtained from numerical analysis using PLAXIS finite element modeling. The results are presented in terms of the wall deformations and bending moments. The obtained results indicate that finite element modeling technique can yield quite safe design measure of cantilever sheet pile wall compared to classical methods.
