Laboratory study for influence of clayey soils on wave-induced liquefaction
MetadataShow full item record
In this study, a one-dimensional experimental study for the influence of clayey soils on wave-induced liquefaction was reported. The onedimensional facility was set-up with a vertical cylinder and a 1.8 m thick deposit and 0.2 m thick water above the deposit. Unlike the previous experimental study only use a single soil or clay, this study use sand-clay mixtures as the experimental sample. A series of experiments with 3000 cycles in each test were conducted under numerous wave and soil conditions, which allow us to examine the influence of wave and soil parameters, especially the influence of clay content (CC) on wave-induced liquefaction. It has been confirmed that the deposit will become prone to liquefaction with the increase of CC, while when CC up to 30%, the mixture sand-clay deposit will almost never liquefied.
