The laterally confined consolidation of initially compacted and wetted swelling clay

This paper describes the laterally confined consolidation of an Israeli clay following compaction and swelling on wetting, including measurement lateral stresses. The results tests are compared to those obtained during from initially slurried condition. In comparing compression expansion indices relative vertical, mean stress, it was found that they varied, depending initial, preparation conditions; values approached with decreasing initial dry density. During unloading, were be independent conditions, essentially same as soil. coefficient earth pressure at rest loading, K 0 , compacted then wetted specimens reasonably constant regardless soil but significantly higher than value However, relationship between normalized coefficients rest, '/K overconsolidation ratio, OCR, for
