| Abstract: | In this paper, in order to calculate the surface movement caused by excavations with the finite element method used on a micro computer, the surface movement for the homogenous rock strata is calculated by Fourier integral transformation and the finite element method respectively. By comparing the results calculated by Fourier integral transformation to that by using the finite element method with different size and arrangment for different regions, the determination methods of the size and arrangment of of elements and the calculating region for the finite element method are obtained. |
