Abstract: Seepage of concrete would cause water loss, higher seepage pressure, structural damage, concrete erosion, freeze-thawing, frost-heaving and et al. It badly influences the durability and dam safety. Combined with examples, the paper analysed dam seepage and advanced some seepage prevention measures, for reference.

摘要: 坝体混凝土渗漏不仅造成水量损失、渗透压力升高,还会导致结构破坏、混凝土溶蚀、冻融和冻胀破坏等,影响大坝的耐久性及安全。根据工程实例对渗漏的各种病害进行分析,并对一些防渗措施进行评价。
