摘　　要：分析了引水渡槽槽身裂缝的分布规律和产生的原因,结合其他渡槽防渗加固试验经验,最终确定了以碳纤维加固方案为基础的“减载+防渗”优化方案:渡槽内部先采用聚合物防渗砂浆修复粗骨料裸露的混凝土,再刮涂聚脲防水涂料护面;外部减载后实施碳纤维加固。该方案防水防渗效果良好,可有效延长渡槽的运行寿命。The distribution pattern and causes of the cracks in the aqueduct body is analyzed,and combined with the experimental experience of other aqueducts in seepage control and reinforcement,an optimal scheme of“load reduction+seepage control”based on carbon fiber reinforcement is finally determined:the exposed concrete of coarse aggregate is repaired with polymer impervious mortar inside the aqueduct,and then polyurea waterproofing coating is applied to protect the surface;carbon fiber reinforcement is implemented after external load reduction.The scheme has good waterproofing and anti-seepage effect and can effectively prolong the operation life of the aqueduct.
