Normally Consolidated and Overconsolidated Clays A clay is said to be normally consolidated if the present effective overburden pressure Po is the maximum pressure to which the layer has ever been subjected at any time in its history, whereas a clay layer is said to be overconsolidated if the layer was subjected at one time in its history to a greater effective overburden pressure, Pc' than the present pressure, Po' The ratio Pc / Po is called the overconsolidation ratio (OCR).
