New practical framework for predicting compacted soil behaviour

A/Professor Jayantha Kodikara

Dept. of Civil Engineering, Monash University, Victoria 3800.

Abstract:

The soil compaction is one of the most common activities of civil construction.  It is applicable to construction of fills, dams, roads and embankments. The compacted soils can be subjected to various external and environmental loading after construction.  The external loading can arise from superstructure loading, moving traffic and overburden soils.  The environmental loading can come from the interaction of surficial soils with the atmosphere in forms such as wetting and drying. Under the combination of these loadings, the compacted soils display complex patterns of behaviour such as swelling, collapse, tensile cracking and swelling pressure development against buried non-yielding bodies. The current approaches for predicting the behaviour of compacted soils during subsequent external and environmental loading are, on one hand, are very complex, and on the other hand, are not entirely satisfactory. The seminar will present a new practical framework for predicting the behaviour of compacted soils under these loadings. 

Resume:

 A/Prof Jayantha Kodikara leads the Geomechanics Group at Monash University, which is the largest such group in Victoria with 5 academics, 6 research fellows and 25 PhD students.  He leads research on fundamental analysis of soil/atmosphere/structure interaction problems including unsaturated soil behaviour and applications to modelling of infrastructure behaviour. He has specific research expertise on fundamental topics of fracture in clay during desiccation and external loading as well as in soil compaction. He is also the Research Director on a large collaborative project on the Condition assessment and remaining life prediction of critical water pipes, funded by a consortium of international industry partners to a total cash value of $4m. He has about 160 journal and conference publications and is a Fellow of Engineers Australia and Associate Editor of the Canadian Geotechnical Journal.
