摘要
以邵阳境内的高速公路雪峰山隧道为研究对象,对高速公路隧道病害开展检测。根据现场检测的结果,发现隧道内裂缝主要有荷载变形裂缝、施工冷缝、温度裂缝及干缩裂缝,且总结了不同裂缝形成的原因。针对隧道衬砌裂缝和隧道渗漏水,提出了治理原则和具体的治理措施。对治理后的公路隧道进行现场监测,结果显示,衬砌拱顶收敛值和收敛位移速率随时间迅速减小并逐渐趋于稳定。由此可见,本次处理病害效果良好。
Taking the expressway Xuefengshan tunnel in Shaoyang as the research object,this paper detects the diseases of expressway tunnel.According to the results of field inspection,it is found that the cracks in the tunnel mainly include load deformation cracks,construction cold cracks,temperature cracks and dry shrinkage cracks.Then the causes of different cracks are summarized.Aiming at the tunnel lining cracks and tunnel leakage,the treatment principles and specific treatment measures are put forward.The on-site monitoring of the treated highway tunnel shows that the convergence value and convergence displacement rate of the lining vault decrease rapidly with time and tend to be stable gradually.The treatment effect is good.
