Energy Absorption Level Test of Tunnel Lining Section Crossing Active Fault
Publication: ICTE 2019
ABSTRACT
In recent years, research showed that the tunnels may be seriously damaged when crossing fault zone. Therefore, the anti-shock designation of lining structure in fault zone is particularly prominent. Through the drop-weight test, this paper researched the damping level of the plain concrete lining, reinforced concrete lining, and rubber lining in circular direction. The test data show that the anti- seismic of reinforced concrete is better than plain concrete. The seismic load absorption ability of rubber lining is much greater than concrete lining. Through numerical simulation, we found the energy absorption rate of rubber lining is 42.5% and rubber lining may meet the anti-seismic requirements of tunnel when crossing fault zone.
