WebIn the literature, a number of researchers have been looking for a possible relationship between Cc and Cr indices and general characteristics of clays. A number of parameters appear to have an effect on the compression of clays. One of these parameters is overconsolidation ratio (OCR). WebAug 21, 2024 · Cc and Cr for under consolidated, normally consolidated, and over consolidated soils are (should be) the same. The distinction lies in the value of Pp. In an overconsolidated soil, you'd get about 10 percent the consolidation. . . unless you exceed Pp. Then the load-to-consolidation trends should be the same for both. Hope that helps? f-d
