摘　　要：目前国内外有关堆石坝坝顶溢洪道的工程实例较少,对其结构设计理论的研究也不多,仅有少量的实验。虽然仅有的几个工程实例也取得了一定的成功,但其设计主要是凭经验来确定,并且都还没有经过设计流量考验。从静力学的角度出发,通过对堆石坝坝顶溢洪道(带有水平阻滑板)的泄槽底板进行稳定分析,得出了水平阻滑板长度与其所受各力之间的关系式和安全系数表达式,为今后的工程设计提供理论计算方法,经实例验证该方法是可行的。It is a few projects of crest spillway of rock-fill dam at home and abroad at present- And there is a little study on its structural design theory, and only have some experiments. Though several project instance gained success, their design was based on experience and have not experienced the design flow. This paper proceeds from aspects of statics to analyze the structural reliability of the chute bottom slab with horizontal anti-slide slab of crest spillway of rock-fill dam, and gives the relational expression between anti-slide slab length and each forces and loads, which provides the theory computation techniques in the future. The practice showed this method is feasible.
