Abstract
Introduction. The effects of low-rise building mat on liquefiable site were investigated in this study.
Materials and methods. One-dimensional ground response analyses of a layered sand model profile were conducted using Midas. The UBCS and soil model was used.
Results. The excess pore water pressure and the stress/strain time histories as well as the ground deformation of the numerical model were examined.
Conclusions. With the comparison of the free-field solutions, if the liquefaction occurred, the mat can cause the subsoils to settle more and push the side soils to move laterally, which will yield sway motions of the mat. The deeper embedment of the mat sometimes would help to minimize such phenomenon.
