| Abstract: | In this paper, several problems in dynamic finite element analysis of underground works are discussed, with emphasis on the boundary problem in the finite element method and the model experiment of earthquake analysis. The condition for the use of nonreflecting boundaries is appointed and a new conception of "rigid-circle" is presented for the earthquake. Based on the "rigid-circle" assumption, some treatments for the boundaries of the finile domain are suggested. |
