摘　　要：通过除险加固工程闸墩结构中设置后浇带进行防裂设计,根据混凝土施工期温度控制原理,对比后浇带设置对结构温度和应力的影响,分析后浇带的防裂效果表明:在闸墩中设置后浇带可有效地防止混凝土产生早期裂缝,极具工程实践价值。According to the structure design and construction of post-poured strip in the factual gate frusta, with regard to the theory of tempera-rare controlling of concrete, through contrast of the temperature and stress with post-poured strip and without post-poured strip, the cracks prevention el-feet is analyzed. The result shows setting post-poured strip in concrete gate frusta can control temperamre and prevent cracks arising effidendy.
