摘要
本文探讨了浯溪口水利枢纽工程底孔溢流堰设计与施工中所采取几个的关键技术;其中基于物理模型试验进行底孔溢流堰设计。模型试验结果表明底孔溢流堰设计既能保证水流平顺,过流能力大,又能保证不出现导致堰面发生破坏的堰面负压。此外,底孔溢流堰施工通过采用倒弧面模板和混凝土分区等工程措施可保证堰体混凝土满足强度、抗冲、温控以及平整度等要求。这些技术可为类似工程溢流堰设计与施工提供重要参考。
Several key technologies adopted during the design and construction of the bottom outlet-overflow weir of Wuxikou Wa- ter Control Project are discussed herein, in which the bottom outlet overflow weir is designed based on the relevant physical mod- el experiment. The result from the experiment shows that the design of the overflow weir can not only ensure smooth water flow and large conveyance capacity, but also can ensure that the negative pressure that leads to the damage of the weir surface do not occur. Additionally, through the relevant engineering measures of adoption of the formwork with inverted cambered surface, zon- ing of concrete, etc. , the construction of the bottom outlet-overflow weir can ensure the concrete of the weir to meet the specifi- cations, such as strength, anti-erosion, temperature control, levelness, etc. All of the technologies can provide some impor- tant references for design and construction of the similar overflow weir concerned.
