Foundation of Mathematical Model of Restoring Saturation Coefficient α

This paper analyses and proves that the restoring saturation coefficient α of one dimension extra saturation sediment discharge method and the modified coefficient K of the quasi hydrostatic settlement method are reciprocals each other.On the analysis of the factors affecting the change of α value,the mathematical model of computing the restoring saturaiton coefficient α is set up.By the verification of error analysis,the accuracy and reliability of the model accord with the designing demands,and can be used by the production and design units.
