摘要
输水隧洞分为有压隧洞和无压隧洞,当隧洞衬砌混凝土产生裂缝后,常拌有渗水出现,会严重破坏混凝土结构的安全,影响隧洞的使用寿命;而且裂缝的处理费工费时,增加工程成本并延长工期。因此,软岩隧洞裂缝产生的原因分析及处理的成功经验对工程建设有着积极的作用。
The water conveyance tunnel is divided into pressure tunnel and non-pressure tunnel. When cracks happened after the completion of concrete lining of tunnel, they often produced water seepage, which could seriously destroy the safety of concrete structure and impact the service life of tunnel. The treatment of cracks requires a lot of labors and time, which could increase project cost and delay the construction period. Therefore the cause analysis and successful treatment experience of cracks of soft-rock tunnel plays an active role in project construction.
