Abstract

Abstract

In order to study the stability of airport pavement underpass tunnel structure under aircraft load, a mechanical model of cooperative deformation of airport pavement-base-soil-tunnel lining structure was established, and the stability of pavement-base-soil-tunnel lining structure under aircraft load was deeply analyzed, focusing on the displacement response, velocity response and stress evolution law of tunnel lining structure under the influence of in-situ stress, tunnel dead weight and impact effect of aircraft load. It was found that the dead weight and in-situ stress of the tunnel had great influence on the overall stability of the soil-tunnel structure, while the impact effect of aircraft load was relatively small. The tunnel structure with circular cross section had the best stability; with the increase of buried depth of tunnel structure, the influence of in-situ stress on the stability of tunnel structure was more serious. The higher the concrete strength of lining structure, the better its stability; with the different positions of aircraft loads, the deformation of tunnel structure changed greatly, and with the increase of lining thickness, the impact effect of aircraft loads on tunnel structure gradually weakened.
