摘要
管片接头是盾构隧道受力的薄弱环节,同时接头也是隧道防水的关键部位,隧道发生火灾很可能导致接头部位变形过大,防水功能失效,使得隧道发生渗漏、涌水,对隧道造成毁灭性的灾害,本文在管片接头高温计算模型基础上分析了高温条件下接头力学特性。
Segment joint is the weak link in the shield tunnel under loading. By the same time, the joint is also a key part for tunnel waterproofing. Tunnel fire is likely to lead to excessive deformation of joint which may cause failure of waterproof function of joints and leakage and water gushing and as a result there maybe a devastating disaster to the tunnel. This paper gives the analysis of mechanical properties of joints under high temperature based on joint model under high temperature.
