隧道工程的病害主要体现在渗漏水的问题上,在隧道两端更为严重,路面积水造成行车环境恶化,导致行车中轮胎与路面的摩阻力降低。由于衬砌渗漏水,造成隧道侵蚀破坏,特别是在渗漏水具有侵蚀性的情况下,对衬砌和隧道设备的腐蚀更严重。 The diseases of tunnel engineering are mainly reflected in the problem of seepage water, which is more serious at both ends of the tunnel. The environment of the road is deteriorated due to the running water, leading to the decrease of the frictional resistance between the tire and the road surface during driving. As the lining seepage water, causing tunnel erosion damage, especially in the case of seepage water is corrosive, lining and tunnel equipment corrosion more serious.
