Abstract: In accord with the characteristics of singular integrals in boundary element method for solving problems of thick plates on two-parameter foundation, all formulas for calculating singular integrals are set up by selecting the displacements and stresses which satisfy the governing differential equations in this paper, on the principle of virtual energy. Thus, the problem of calculating of high-order singular integrals in the BEM is solved successfully.

Key words: boundary element method, thick-plates, singular integrals, tow-parameter foundation
