Elastic Analysis of Urban Tunnelling Ground
초록
영어
The finite element method and the boundary element method are applied to analyze stress and deformation developed in the elastic ground which an urban tunnel with various section is excavated. The anaIytical results by both the finite element method and the boundary element method show relatively good agreement with Mindlin
’s solution. And this paper shows that the boundary element method is more favourable than the finite element method because the work to obtain same accuracy is simple and computing time is short.
Also, to establish a reasonable design method for urban tunnel. minute investigation is carried out to variation of stress deformation around tunnel, subsidence and heave of ground etc.
