Experi mental study on the longitudinal joint of shield tu nnels reinforced with co mposite cavity
摘要
Abstract
According to the conditions of shield tunnel operation,the open-angle of the joint often exceeds the design requirements in the ling rings with large deformation,which should be reinforced in time to control the de-formation.As a new reinforcement material,composite cavity has the characteristics of light-weight and rapid reinforcement,which can be quickly applied to metro tunnels.A full-scale test was carried out to study the ul-timate bearing capacity of the reinforced longitudinal joint and that of the unreinforced.The failure mechanism of reinforced joints with composite cavity was obtained and the overall effect of the reinforcement was evaluated.The results obtained are in well accordance with the previous findings and can provide reference value to similar engi-neering projects.关键词
