Effect of Sandy Ground Structures upon Earthquake-Induced Damage to Various Objects

Abstract eng:
To make clear the structures of sandy grounds on which various objects are liable to be damaged by liquefaction what is called and the damage mechanism, much damage to embankments, buildings, bridges, slopes, quays, power substations and so on have been investigated. In this paper, a liquefaction-induced damage mechanism is studied comparing the deformation of objects and grounds with structures of grounds. It is presumed that most of the damage was caused by large differential displacements due to uneven thickness of soft clayey layers within grounds and by sliding displacements occurring in thin and equally soft clayey ones.
