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。现从结构可靠度分析的角度出发,通过应用JC法对堆石坝坝顶溢洪道带有地锚加固泄槽底板结构的可靠度进行分析,进一步说明了堆石坝坝顶溢洪道的泄槽底板采用地锚形式的加固措施是安全稳定的,此结构形式是可行的,为今后的工程设计提供理论依据。
There are a few projects of crest spillway of rock-fill dam at home and abroad at present.There is little study of their structural design theory and experiments from the aspect of structure reliability analysis,the structural of the chute bottom slab with anchored is analyzed by JC method in this paper.It shows that to reinforce the chute bottom slab of crest spillway of rock-fill dam by anchorage method is stable and safe,and the structure is feasible.It also provides the theory base for engineering design in the future.
