Seepage control of unsaturated soil based on the SWCC

The change course of the soil in the foundation under the reservoir will change from natural state to unsaturated state to saturated state because of the increase of water content after sluice of the reservoir.The change course has been analyzed with the FEM of unstable and unsaturated base on the results in the lab.The engineering geology is influenced greatly by the course.The effect of the cut seep dyke can minish the influence of the change course.Based on the SWCC obtained from the test dat...
