摘要
坝高作为橡胶坝的一项重要参数,对橡胶坝塌坝泄水和立坝蓄水具有显著影响。通过物理模型试验的方法设计6种坝高的充水式橡胶坝,对影响坝高的主要因素坝袋充水量和堰顶水头进行试验研究并分析其间的关系,拟合出经验公式。结果表明,橡胶坝坝高随坝袋充水量的增加而变高;当实际坝高未达到设计坝高时,在同一坝袋充水量下,坝高随堰顶水头的增大而变高;当实际坝高等于设计坝高时,堰顶水头对坝高的影响变小,坝高几乎不再随堰顶水头变化。
Dam height has a significant impact on the function of water storage and discharge,which is one of the most important parameter of the rubber dam.Physical model experiment was used to design water filling rubber dam with six dam heights.And then the relationship between dam height,volume of filling water and weir head was analyzed based on the experiment.Then the empirical formula was fitted.The results show that the greater volume of filling water is,the greater dam height is;when dam height does not reach designed value,dam height increases with the increase of weir head in the same volume of filling water;when dam height reaches designed value,the impact of the weir head will be reduced and the dam height will not be changed.
