Effects of geomorphological and hydrological changes on piles supporting riverine infrastructure

By U. Ahmed and Dominic Ek Leong Ong

Abstract

In recent times, several cases of foundation failures associated to riverine structures such as jetties, bridges and wharfs have been reported. The geomorphological changes and hydrological changes of river bank slopes have been found to induce progressive soil movements before first time failure of the slope occurs. These cumulatively large movements can result in additional deflections and bending moments on the pile. The subsequent reduction in soil resistance due to the repeated soil movement patterns caused by these change has the potential to threaten the structural integrity of the pile. This paper presents a state of the art review of the recent developments in understanding soil-pile interaction for piles located in river bank slopes subject to soil movements induced by geomorphological and hydrological changes.Full Tex
