Changes in the Engineering Properties of Reconstituted Ariake Clay Undergoing Drying

摘要

Most natural clays exhibit overconsolidation histories to some degree due to processes of mechanical unloading such as erosion, excavation, changes in groundwater pressures, desiccation, etc. In the present study, we focused on the effects of shrinkage histories due to desiccation caused by sea level regression on the engineering properties of Ariake Clay. The soil stratum consists of a Holocene clay deposit. This paper describes an experimental investigation of the engineering characteristics of reconstituted Ariake clay subjected to differing desiccation histories. We have found that the engineering properties of Ariake clay are strongly influenced by shrinkage due to desiccation.
