Abstract
The present paper deals with the effects of liquefaction-induced lateral flow on in-ground structures, focusing on the load characteristics of ground lateral flow. For this purpose, a shake table test, an upward seepage flow test and numerical analyses are conducted. The results from the tests and analyses demonstrate that a drag force from ground lateral flow is the essential effect if complete liquefaction occurs around in-ground structures. It is also shown that the drag force has an insignificant effect on in-ground structures when the size of liquefied area is considered to be relatively small comparing to the spatial extent of an in-ground structure.
