expansive soils are of the kind the volume of which will be changed to extremes by being exposed to varying conditions of moisture. this volume change is a serious menace to structures built on these types of soils. throughout the present research the potential of volume change in these soils was investigated when exposed to the phenomenon of wetting and drying. for the purpose, samples of a st...

Abstract The understanding of the weakening mechanism tensile strength rock subjected to cyclic wetting-drying is critical for engineering. Tensile tests were conducted on a total 35 sandstone specimens with different cycles. crack propagation process and acoustic emission characteristics tested samples obtained through high-speed camera system. results indicate that observably reduced after we...

Previous studies indicate that post-compacted changes in moisture and suction significantly influence small strain response, often this is not routinely monitored during operation. Thus, assessing the impacts of seasonal variation on performance critical for gauging geomechanical behaviour compacted soils underlying typical transport infrastructure. In paper drying-wettingcycles stiffness inves...
