Abstract
The rapid increase of transportation makes it necessary construct shallow burial Tunnel under skew-crossing highway in China. Thus, the prediction of the influence on the safe operation of skew-crossing highway in the tunnel construction plays a key role in the optimal design and construction of tunnels, to avoid any damage to the existing highway during and after tunnel construction. In this study, the numerical analysis combining with the case in Fujian province, P.P. China, using finite element program ABAQUS, has made it possible allow for the situation of the tunnel under skew-crossing highway with a small angle. The influence of cover plate on the safe operation of highway in shallow burial tunnel construction was researched. The study results are shown as follows: the construction of tunnel has great impact on the operating highway; the larger the vehicle load on the highway, the greater the settlement of highway; the use of cover plate may be the effective measure to control the highway settlement; there is an zone of highway settlement influenced by cover plate stiffness and vehicle load, beyond which their influences on highway settlement are greatly reduced. The influence of the distance between tunnel face and highway on the safety of highway in operation has also been highlighted.
