Study on Dynamic Characteristics of Circular Tunnel Concrete Lining

Abstract:

The dynamic characteristics of concrete lining of a circular tunnel was studied combined with the Dahuofang water-conveyance project. The first ten frequencies and modes of vibration were presented. The influence of some factors on the vibration performance of the concrete lining were analyzed, i.e. buried depth, lining thickness, youngs modulus of rock, and water in the tunnel. The results show that the buried depth and the youngs modulus of rock have greater influence on the vibration performance of concrete lining than the lining thickness and the water in the tunnel. Some aseismic measures are given out for the similar engineering.
