Performance Verification of Design Method for Plain Concrete Linings and Inverts Assuming Ground Displacement after Completion

Abstract

There are various structures in railway systems. These structures including tunnels need to have the same level of performance and their performance should be verified quantitatively. Therefore, we proposed a method for verifying the performance of plain concrete linings and inverts, and developed a trial design assuming a mountain tunnel receiving ground deformation after completion. In the trial design, we imposed the displacement to the lining and invert using a ground deterioration model. As a result, it was found that the performance can be verified using the proposed method, and that the required performance can be satisfied by adopting strong invert structures against floor heave.
