Numerical Analysis of the Building Base Stabilization Change by Tunnel
Aiming at the geological condition in mining area, researches the movement of earth and the surface subsidence caused by the tunnel by using the nonlinear finite element method, summarized the earth stress and the deformation distributed law under the surface building. The result indicated that, the tunnel has a development process, the subsidence depth, the inflection point of submersion basin and the stress distribution presents the obvious change along with it, and easy to cause the surface building foundation instability, even cataclysm. The rectification method by punching holes in deep is possible to drive the few subsidence side soil under the base with uniform speed, to reduce the building to incline and to relieve the uneven base stress, and has the application value to the incline building with this disaster.
