摘要
隧洞衬砌混凝土产生裂缝后,常拌有渗水现象,会严重破坏混凝土结构的安全.裂缝产生的原因、防治及处理的方法直接关系到隧洞的使用寿命.现以永宁河四级水电站引水隧洞为例,分析裂缝产生的原因,给出了裂缝的处理方法及预防措施,同时指出隧洞混凝土衬砌不仅要考虑岩石突出或夹角部位对裂缝产生的影响,还要考虑混凝土内部应力.
The lining concrete cracks in diversion tunnel have great influence on concrete structure safety because of ooze water.The causes of cracking and fissuring prevention as well as treatment methods are directly related to tunnel serving life.The causes of the cracks and preventive measures are analyzed in the essay,taking Yongninghe Level 4 Diversion Tunnel for example.It is illustrated that protruding rock or angle parts should be taken into consideration in concrete lining,and inner stress as well.
