Effects of various factors affecting the settlement due to submergence of sandy soils

摘要

In this paper, a series of laboratory tests using a total of seventeen sandy fill materials was carried out in order to discuss the effects of the degree of compaction, initial water content, overburden pressure and the stress history on the behavior of one-dimensioal subsidence when the soil is submerged. As a result, it was manifested that the subsidence was greatly influenced by four factors; i.e., the degree of compaction, Fine fraction content, the initial water content and the overburden pressure. In addition, The total volume strain when the degree of compaction of the initial is the same and the overburden pressure and the water content each monotonically increase to approach the saturation state do not depend on the initial water content of the specimen, the history of water immersion and overburden pressure, The final overburden pressure turned out to be uniquely determined.
