Flat Rate Mechanical Optimizational Analysis of Four-Lane Tunnel with Single Arch Based on Load Structure Model

Abstract:

In order to analyze the influence of flat rate on mechanical character of large-span tunnel structure, the structural analysis of three flat rates in four-lane tunnel with single arch is progressed by the compiled procedure of load structure model. The result shows that the lower flat rate is, the more unfavorable structural stress is and the more unstable surrounding rock is, the optimal flat rate of four-lane tunnel is 0.65.
