Abstract

Aiming to improving the out-of-plane instability of I-steel arches in large-section tunnels, this study conducted the full-scale test of a single arch, the numerical test of the arched frame structures formed by the longitudinal connections and the arches, and the field comparison test. The results indicated that the failure mode of the single arch was local out-of-plane instability, leading to a loss of overall bearing capacity. The in-plane bearing capacity and out-of-plane stability of arched frame structures considering longitudinal connection bearing capacity are enhanced. In addition, the bearing capacity of the primary support can be fully utilized by adjusting the longitudinal connection spacing and the arch spacing to improve the internal force sharing ratio of the arched frame structure and the shotcrete. However, the longitudinal connection spacing should be less than 1500 mm, and the arch spacing should be less than 1200 mm. Therefore, without changing the existing structural form of the primary support, the arched frame structures with spatial bearing effect formed by rationally arranged longitudinal connections and arches can not only ensure the bearing capacity of the primary support, but also improve construction efficiency and economic benefits. The research findings can guide the structural design of primary support for large-section tunnels.
