FUNDAMENTAL STUDY ON ISOLATION SYSTEM OF THE SHIELD TUNNEL BACX-FILLED WITH SPECIFIED MATERIALS
|
´˜^i‰pjF
This paper describes the isolation system of shield tunnel back-filled with specified materials. Its basic theory was cleared through the experiment. On the basis of it, the influence of the rigidity of tunnel, surrounding ground and back-filling materials upon the tunnel was analyzed with FEM. As a result, the characteristics of back-filling materials effective to reduction of seismic stress of shield tunnel were obtained.
