Determination Methods of Ultimate Displacement Values of Tunnel Based on Bearing Capacity of Primary Supporting Structure
The limit states of a primary supporting structure were used to represent the limit states of the tunnel, and the analytical methods of Catastrophe Theory and bearing capacity were respectively used to determine the ultimate displacement values of the tunnel. The calculated results indicate that the ultimate displacement values obtained from the two methods are close to one another, and it is suggested to use the analytical method of bearing capacity, which is with explicit mechanical basis and small values. On surrounding rock, the effects of such parameters as resistance coefficient and side pressure coefficient were analyzed, and the results show that the effects of two parameters on the ultimate bearing capacity of the structure are great, but small on its ultimate displacement values. This paper proposed the determination method of the ultimate displacement values of a tunnel. The method directly correlates with the parameters of the primary supporting structure of the tunnel and is with explicit and reliable calculated results. Therefore, the application of the method can be spread to the determination of the ultimate displacement values of a tunnel in its displacement monitoring.
