但由于设计、施工、维修养护、验收等各方面的原因，相当比例的隧道都存在着不同程度的病害问题，甚至一些隧道刚竣工即出现大量的衬砌病害问题。如果隧道内出现严重渗漏水、衬砌开裂等情况,就会大大降低结构的安全可靠性,影响隧道正常运营，进而使整个交通线处于完全中断状态,给公路交通造成严重的经济损失和恶劣影响。因此为保证运营隧道结构的耐久性和行车过程中的安全舒适性，对存在病害或病害隐患的隧道进行检查、养护工作成为亟需开展的工作。

結果 (英文) 1:

But because of the design, construction, maintenance, inspection, and other reasons, a considerable proportion of the tunnel there is a varying degree of disease problems, and even some disease of the lining of the tunnel has just completed a large number of problems. If severe water leakage in tunnels and lining cracks of status, it will greatly reduce the security and reliability of structures, affect normal operation, thus making the lines are totally broken, cause serious economic damage to highway traffic and adverse effects. To guarantee the durability of tunnel structure and driving safety and comfort in the process, disease or disease risk checks of tunnels,The conservation work needed work.

結果 (英文) 2:

However, due to the design, construction, repair and maintenance, inspection and other aspects, a considerable proportion of the tunnel there are different degrees of disease problems, and even some newly completed tunnel lining appears a lot of disease problems. If severe leakage of water, lining cracking happens inside the tunnel, it will greatly reduce the security and reliability of the structure, affecting the normal operation of the tunnel, and then the entire transit is completely disrupted state highway traffic to cause serious economic losses and adverse effects . So driving the process to ensure the durability and operational safety of the tunnel structure in the comfort of the presence of disease or disease hazards tunnel inspection, maintenance work became urgent work carried out.

But due to various reasons, the construction design, repair and maintenance, inspection, a considerable proportion of the tunnel there are problems in different degree, and even some tunnel has just completed a large number of problems that appear lining disease. If the tunnel serious seepage Water Leakage, lining crack, it will greatly reduce the safety and reliability of the structure, influence the normal operation of the tunnel, thus the whole traffic line is completely interrupt status, cause serious economic loss and bad influence to the highway traffic. So to guarantee the operation of the tunnel durability and traffic safety in the process of comfort, to examine the existence of hidden disease or disease of the tunnel,Maintenance work has become urgent work.
