摘要

A newly proposed composite tunnel structure is composed of H-beams in soil cement and reinforced concrete for sidewalls in a cut and cover tunnel. In order to investigate the seismic performance of the corner part in new proposed composite tunnel, a reversed cyclic loading test was carried out using an L-shaped model specimen. Next, numerical analyses were carried out using a fiber model and FEM, aimed at establishing a method for analyzing the structure. As a result, the proposed structure has a sufficient seismic performance and can be kept as the integration during an earthquake. It also has a sufficient deformable capacity and a high ductility up to the ultimate state. Furthermore, the numerical methods can simulate the proposed structure with high accuracy.
