Abstract

Abstract

The filling karst raft roadbed reinforcement of the tunnel bottom in DK278 + 628- + 698 section of a railway is analyzed by three dimensional elasto-plastic contact finite element method. The Drucker-Prager model and elastic-plasstic contact model is used in simulating the stress, deformation and strain of the tunnel. And the resuh has guiding significance on the engineering.
