| Abstract: | According to the rule of soil pressure varying with displacements, a new model of calculating soil pressure is presented. Combined with the newly presented model and the interaction of ring beam and piles, a computation program is made in Matlab Language. A typical case is calculated by the program, which verifies the advantage of the method. |
