CANTILEVER SHEET PILE WALL By Lakshmi Radhakrishnan Email id: lakshmiradhakrish@gmail.com ABSTRACT: A sheet pile wall consists of a series of sheet piles driven side by side into the ground‚ thus forming a continuous vertical wall for the purpose of retaining an earth bank. They are commonly used for: (1) water front structures‚ (2) temporary constructions‚ (3) light weight construction where sub soil is poor for supporting a retaining wall. A sheet pile may be of three types: Cantilever
