Failure mechanism of segmental lining structure in fault-crossing tunnel: An experimental and numerical investigation

Abstract

With the rapid development and construction of tunnel engineering across active faults, the analysis and design methods for crossing-fault tunnels urgently need appropriate theoretical guidance. Under the action of fault dislocation and ground motion, the influence law and failure mechanism of segmental lining structures with different lengths were explored via shaking table model test and numerical simulation. The results show that the structural relative displacement between the hanging wall and the fracture zone is reduced, accompanying by the decrease of lining longitudinal connection stiffness, while the variation tendency of structural relative displacement between the footwall and the fracture zone is to the contrary. Therefore, the lining segments near the hanging wall should be divided into smaller segments, and the lining segments near the footwall should be larger according to engineering requirements. Combined with the test results, the fortification range of the affected zone near fault is proposed. The function of lining joints should also be considered when dividing the length of segments, so that the smooth transition of longitudinal lines under the affection of fault dislocation can be realized. It is found that the failure evolution process of numerical simulation is well coincided with the result of shaking table test.
