- Description
- Developments in the the mechanics of unsaturated soils are investigated in relation to current engineering standards/practice. The behaviour of unsaturated soils is exceedingly complex and the behaviours experienced are not easily explained using 'classical' saturated soil mechanics principles. Jennings and Burland (Jennings and Burland, 1962) established that Terzaghi's (1936) principle of effective stress was invalid for clayey soils with degrees of saturation less than approximately 90%. Depending on the stress range, samples may either shrink (collapse) or swell (heave). This potential for collapse of compacted soils was recognised by Lawton et al. (Lawton et al., 1992) as being poorly understood area by geotechnical engineers. In semi-arid climates, like much of Australia, the development of unsaturated soil mechanics can play an important role in safe and economical design of infrastructure.
