Nisheeth Shrivastava,Chiranjeeb Buragohain of lime. In the paper, results from Mercury Intrusion Porosimetry (MIP) on a lime stabilised dynamically compacted natural silty soil are reported. Those results highlight the time dependency of modifications induced by lime on the microstructure, which is strongly related to the initial moulding water content of the sample.作者: 知識分子 時間: 2025-3-22 10:41

Fabric Changes in Compacted London Clay Due to Variations in Applied Stress and Suctionrangement of particles, using Environmental Scanning Electron Microscopy. The study showed important changes to take place in the soil micro-fabric during wetting, whereas the effect of loading was seen to be less severe. The results suggest that changes in the overall micro-fabric of a compacted clayey soil are strongly stress path dependent.作者: 沙發(fā) 時間: 2025-3-24 23:16 作者: tic-douloureux 時間: 2025-3-25 05:42

Shear Strength Affected by Suction Tension in Unsaturated Fine Grained Soils?. The development of pore pressure in a completely water saturated grain structure will reduce the shear resistance, whereas the suction tension within an unsaturated soil will cause additional grain-to-grain forces.
