Abstract
It is significant to study the tunnel mechanical behavior induced by excavation and support in order to ensure the safety and economy of the tunnel engineering. First of all, in order to take into account the effect of the intermediate principal stress on the tunnel mechanical behavior, the unified strength criterion is adopted to describe the plastic yield behavior of the surrounding rock. Secondly, the model proposed by Kastner does not consider the co-effect of the initial elastic displacement of the tunnel surrounding rock before the support structure is installed and the interaction between the surrounding rock and the support structure. Therefore, a new analytical model for the circular tunnel, which can overcome these two shortcomings, is proposed by accounting for the tunnel practical construction process on the basis of Kastner’s method. The effects of the calculation parameters such as the intermediate principal stress coefficient b, the initial elastic displacement u0 of the tunnel surrounding rock, the rock mechanical property and the stiffness ks of the support structure on the surrounding rock plastic zone, the radial displacement of the tunnel inner wall and the support stress are studied in detail. The results show that the proposed model for the circular tunnel, which considers the co-effect of the intermediate principal stress and interaction between the surrounding rock and support structure, can perfectly reflect the tunnel mechanical behavior. Finally, the proposed model is verified with the practical tunnel engineering.
