摘要
水工隧洞混凝土衬砌是隧洞施工中的重要环节,如果施工过程采用措施稍有不当,衬砌混凝土就会产生裂缝,而衬砌混凝土裂缝不仅影响隧洞的结构稳定,还会因裂缝漏水影响隧洞的运行安全。以二道弯隧洞为例,提出应在施工过程中分析混凝土裂缝产生的原因,采取相应的措施,预防混凝土裂缝的产生。
Concrete lining of water tunnel is an important step in tunnel construction. If improper treatment is made during construction, crack may happen that not only has negative impact on the stability of tunnel structure but also result in leakage that affects the safety of the tunnel. Taking Erdaowan Tunnel as an example, the causes of lining concrete cracks during tunnel construction are presented and relevant measures are given for preventing the happening of lining concrete cracks.
