Earth retention systems such as retaining walls are versatile structures used extensively across the civil and construction sectors. Although the methodologies used for wall design can be considered fairly simplistic, wall failures are a surprising common occurrence in the civil construction industry.

This dissertation sought to examine the prominent retaining wall systems used in South-East Queensland and investigate the various theories employed to define their strength requirements. It identifies the bored pier retaining wall as having inherent issues with failure throughout the South East and identifies an appropriate design methodology to undertake theoretical analysis of current practices.

The study shows that there is a lack of unified understanding within the engineering practice regarding element capacities and the lateral earth pressure loadings for bored pier retaining walls. Alternative design iterations used in the industry are compared with the results of the completed design analysis. The results indicate poor performance with regard to soil failure and flexural capacities.

It is hoped the recommendations of this study be considered by regarded members of the engineering profession and lead to a unified understanding and design methodology for bored pier retaining walls. Improvements to the performance of these walls will greatly reduce the failure rates within the civil construction industry.
