摘　　要：通过对隧道病害形成的环境条件和结构条件进行分析,研究病害产生的原因。提出隧道病害按不同荷载形式、病害表现和发展程度划分为4个补强等级。给出隧道病害的三种主要处治方法及不同等级病害相应的通用处治方法。对垂直荷载引起的病害进行数值模拟计算,其结果与现场实测结果相互吻合。By analyzing environmental and structural conditions of tunnel defects, causes of defects are studied and four reinforcement grades for tunnel defect are put forward according to different load form, defect behavior and development degree. This paper presents three different solutions for tunnel defects and general treatment examples corresponding to different grade defects. In addition, numerical simulation for defects due to vertical load is carried out and results of computation agree well with the results of in-situ test.
