| Abstract: | This paper discusses the boundary element method the application of the in-out boundary element method to compute the problem of reverse evaluation of the load (counter-force) with the known displacement (deformation) . It provides an easy and feasible method to solve the problem of complicated boundary condition in engineering. It also analyses the pressure distribution on the country rock of the tunnel support with examples. It provides an important reference to the design of the underground engineering and the research of the underground pressure. |
