The deformation and stress induced by the loading of building on the foundation will cause the settlement and incline.If the foundation settlement isn't a uniform one,it will decline and affect the safety of the building.The consolidation coefficient is the main factor for the settlement of foundation.At present,the method for the consolidation coefficient such as logarithm of time and square root of time methods couldn't overcome the jamming.However the Genetic Algorithm can diminish the jamming and a precise result can be gained.
