- Abstract
Lining crack is a primary disease in water conveyance tunnel engineering, and accurate analysis of the stability of lining structure with cracks is critical. Based on the theory of fracture mechanics, the contact model has been used to simulate the contact friction effect of crack surfaces. Combined with the fracture criterion of concrete, the safety evaluation methods for tunnel lining structure with cracks has been established. Taking a water conveyance tunnel for water diversion project as an example, the paper analyzes the influences of crack position and crack angles on the safety of lining structure based on calculating models, and the influences the stability of the tunnel lining with cracks.
