DESIGN OF DEEP EXCAVATION WITH DIFFERENT METHODS

Abstract

As of excavation supporting methods, sheet pile walls for supporting earth are commonly used. In this report, a validated 2-dimensional finite element (FE) model was used to test lateral earth pressure distribution on sheet pile walls, as well as an empirical approach derived from Peck and Terzaghi 1967, with the goal of comparing numerical modelling and empirical sheet pile wall design. Finite element analysis can be used to calculate the factor of safety for excavations. The results of the research were helpful in the development of safer and more cost-effective sheet pile walls. The empirical method has a limitation that they can be used for a the same type of problem for the problem with special or new design such as any ground stabilisation or cross wall or two approaches are mixed while design than the empirical method can lead to incorrect design.
