Abstract

At present，the calculation method of foundation settlement in engineering mainly depends on the method in the standard. The compression modulus is used to calculate the compression settlement by the stratified sum method，and then multiplied by the empirical coefficient. The empirical coefficient is 0.2–1.4，The coefficient range is too large. In order to solve the problem，new method is proposed. The deformation modulus is proposed for the hard soil foundation instead of the compression modulus，so the empirical coefficient can be canceled. And the empirical method to determine the deformation modulus is proposed. For the saturated soft soil，it is recommended to calculate the correction coefficient based on the load level or the stability safety factor rather than by human experiments. So as to provide a simple and practical engineering settlement calculation method for engineering. Case study shows that it can effectively improve the accuracy of calculation settlement.

Key words： foundation engineering ground settlement layer summation method deformation modulus compression modulus
