Examining the seismic behaviour of partially saturated sand using centrifuge shaking table tests

Examining the seismic behaviour of partially saturated sand using centrifuge shaking table tests

Similar to fully saturated sand, the partially saturated sand can also liquefy under certain conditions during earthquakes. This study aims to characterize the seismic behaviour of partially saturated sand. Centrifuge shaking table tests were performed using the IWHR horizontal-vertical centrifuge s...
