摘　　要：由于现行水工隧洞设计施工规范中,尚无明确的针对隧洞在运行阶段出现裂缝后进行修补的设计方法和施工规程。因此,文章结合某境外水工隧洞的衬砌混凝土开裂问题,对水工隧洞钢筋混凝土衬砌开裂的加固设计方法进行了研究,并提出了相应的修补措施,通过计算验证了该方法的正确性。该计算基于有限元数值方法,通用性较强;修补措施简单有效,施工方便,确保工程的安全运行。In currently-applied specification for design and construction of the hydraulic tunnel,design methods and construction regula-tions for remedying cracks in tunnels at its operation station are not available. In the paper,therefore,the crack remedying of the lining concrete in a hydraulic tunnel abroad is exampled. The design methods for strengthening the cracks in the reinforced concrete of the hy-draulic tunnel are studied and the corresponding remedying measures are proposed. Through calculation,correction of the remedying method is proved. The calculation is based on the finite element numerical method and with strong universality. The remedying measure is simple and effective,the remedying construction is convenient as well. The safety operation of the project is secured.
