Abstract: When exploring the stress solution of settlement calculation for the special shaped foundation, based on the measured data of the model foundation this pa-per researches the non-linear model type of the stress problem, and it is direc-tly used in the settlement calculation in the Beijing International Hotel pxoj-ect and the calculated values are found to have closer agreement with measur-ed values. As the constitutive relation of the soil is not known and has not been put into practice, this is a practical method to solve the non-linear stress distributioi. problem of the actual project. It can be increased the accuracy of the settlement calculation, and the special shaped foundation is especially app-licable.
