| 摘 要： | 渡槽水封止水带广泛应用于水工建筑的接缝处，用于防止建筑物漏水。止水带的性能老化失效不但会对供水效率和供水沿线生产生活环境造成影响，而且对整个渡槽的安全稳定也有重要的影响。该文以渡槽水封止水带为主要研究对象，研究pH值、温度、紫外线等因素对止水带性能的影响，试验表明：温度对止水带的性能影响很大，温度越高，止水带的老化速度越快；浸泡在酸性溶液中，止水带的性能会有下降趋势；紫外线的照射会加速止水带的老化。

| Abstract: | Rubber water-stop for Aqueduct is widely used in hydraulic architecture to prevent leakage .The test on the effects of pH , temperature, ultraviolet radiation and other factors on rubber water -stop.The results show that temperature had a great influence on water-stop, The higher the temperature is , the faster the water-stop＆#39;aging is; being immersed in acidic solution , water-stop＆#39;s per-formance will decline;ultraviolet radiation will accelerate the aging of the water-stop. |

| Keywords: | Aqueduct Water-stop Tensile strength Break elongation Hardness |
