为了解决长时间季节性暴雨后,运营隧道易出现病害的问题,对长时间季节性暴雨后高速公路某运营隧道发生的病害进行调查、监控、数值模拟及分析。研究结果表明:1)长时间大暴雨后,隧道病害关联性存在,表现为渗漏水、基底隆起、翻浆冒泥、中央排水沟堵塞以及衬砌变形破坏;2)排水系统堵塞后,隧道衬砌结构上水压力和内力急剧增大,隧道率先在仰拱和墙脚处出现破坏;3)隧道渗漏水病害采用凿槽引排,变形破坏段采用分段逐步换拱和仰拱施作,整个隧道采用中央排水沟扩挖、沉沙井和排水系统疏导的方法;4)病害整治期间隧道结构变形较小、收敛,结构安全,整治措施合理可靠。
為瞭解決長時間季節性暴雨後,運營隧道易齣現病害的問題,對長時間季節性暴雨後高速公路某運營隧道髮生的病害進行調查、鑑控、數值模擬及分析。研究結果錶明:1)長時間大暴雨後,隧道病害關聯性存在,錶現為滲漏水、基底隆起、翻漿冒泥、中央排水溝堵塞以及襯砌變形破壞;2)排水繫統堵塞後,隧道襯砌結構上水壓力和內力急劇增大,隧道率先在仰拱和牆腳處齣現破壞;3)隧道滲漏水病害採用鑿槽引排,變形破壞段採用分段逐步換拱和仰拱施作,整箇隧道採用中央排水溝擴挖、沉沙井和排水繫統疏導的方法;4)病害整治期間隧道結構變形較小、收斂,結構安全,整治措施閤理可靠。

When long-duration seasonal rainstorms happen, diseases are easy to occur to operating tunnels. In the paper, the diseases that occurred to a highway tunnel after long-duration seasonal rainstorms are investigated, monitored, numerically simulated and analyzed. Conclusions drawn are as follows:1) After long-duration rainstorms, inter-related diseases, such as water leakage, floor uplift, mud pumping, central drainage ditch blocking and lining deformation, occur to the tunnel;2) When the drainage system is blocked, the water pressure on the tunnel lining and the internal force of the tunnel lining increase rapidly, which leads to the damage to the invert and the side wall feet;3) The following treatment measures are taken:Channels are cut to guide the ground water out so as to eliminate the water leakage disease; the damaged lining is removed section by section, new lining is installed and the invert is reconstructed;the existing central drainage ditch is widened, new sand collection shafts are installed and the drainage system is improved;4 ) During the treatment of the tunnel diseases, the deformation of the tunnel structure is small, which demonstrates that the tunnel structure is safe and that the treatment measures taken are reasonable and reliable.
