The importance of settlement can easily be understood, as excessive settlement will only create a serviceability problem, but will also adversely affect the integrity and stability of the structure. The significance of the soil consolidation process to the structure is that it can induce substantial settlements in the long term under the loads of the structure which is required to be estimated for both ultimate and serviceability design considerations. A further discussion of the consolidation theory is given, following the theory developed by Terzaghi. Actually, from Equation, if the stress change is small, it can be approximated as: The volume compressibility can hence be approximated as: Since the effective overburden stress can change several times during the reclamation consolidation process, the volume compressibility will also change several times. The codes often stress that settlement and relative settlement should incur detrimental effects to the structures, both in the ultimate and serviceability limit states.
