Abstract

The development of Constant Plastic Index (CPI) method is an approach model based on the
theory of consolidation. The objective behind the development CPI method is to predicts critical state
settlement whereby CPI is to achieved secondary settlement and reduced time of consolidation. The
development CPI has been derived base on the ultimate soil settlement where soils are classified
accordingly using initial void ratio, final void ratio and thickness of soil layers. The linear and non linear
soil was developed by the relationship between an exponential stress - void ratio and the parabolic
permeability – void ratio. The external forces is normally consolidated soil layers and develop Stratum
index factor (SIF) and Void ratio function(VRF) which is composed of such a soil varies non- linearly
in deposition. Development of CPI will used to predicts critical state settlement, using Eurelian method
By combination of these elements, the Potential Instability of settlement was develop and integrate
CS- Rating makes concerted effort to produce CS- statement guidelines and better design strategy for geo -
mechanics engineer to involve in soil development settlement analysis. Finally, modification of CPI
method can be determine soil settlement by using CS- Rating.
