Experimental Study on the Carrying Capacity of Lining Structure of Hydraulic Tunnel

Abstract:

In this paper, a large-scale indoor model test with water pressure is conducted in order to investigate the stress and deformation properties of reinforced concrete lining structures with circular cross-sections.Under internal water pressure, the water pressure carried by lining structure is about 20%~40% of total water pressure before cracking and less than 30% after cracking.Under external water pressure, without drainage of outer side of lining, the water pressure carried by lining structure is only less than 40% of total water pressure.
