According to the theory of structural mechanics, elastic mechanics finite element method and boundary element method, five kinds of calculation models of underground buried pipe structure with rigid foundation are established, and compared with the engineering examples, the applicability of each method is pointed out And its shortcomings.It is suggested to adopt the method of structural mechanics when designing the initial scheme of the buried underground pipe structure, to adopt the finite element method when designing the concrete scheme, and to use the boundary element method as the auxiliary design method
