In order to obtain the empirical coefficient of settlement calculation for building foundation in Yinchuan area, Select multiple engineering sites in Yinchuan area, The final settlement of foundation is calculated by using the method of stratified summation and the nonlinear finite element software ADINA respectively. The settlement calculation results are compared and the differences between the two methods are analyzed. Comparing the calculated results with the measured average settlement of building foundation, got empirical coefficient of settlement calculation. Under the condition that the confidence level is 95%, Bootstrap method is used to deduce the confidence interval of the corresponding settlement calculation empirical coefficients of the two methods are [0.090, 0.142] and [0.055, 0.092] respectively. The confidence interval of the settlement experience coefficient can be used as reference for the engineering technicians in Yinchuan area.
