Abstract
The design of T-shaped cantilever retaining wall and support system requires careful analysis especially the geometry of the wall. The design starts by proportioning the wall dimension for which stability is checked for. Commonly, limit equilibrium method (LEM) is used to analyse the performance, however, the LEM analysis unable to predict the displacement of the wall. Thus, the numerical analysis using finite element method (FEM) incorporated in Plaxis software computer program was adopted to analyse the behaviour of the T-shaped cantilever retaining wall. This chapter describes the performance of a cantilever wall with different geometry parameter to predict the displacement pattern of the wall and the distribution of lateral earth pressure. Plain strain condition with 15 nodded triangular elements have been chosen in modelling the wall using Plaxis 2D. The result of the analysis indicates the lateral earth pressure distribution depended on the height of the wall. While the displacement of the retaining wall system showed the reasonable agreement with the recommended design of the geometry ratio.
