| 摘 要： | 反拱水垫塘是一种新型消能防冲结构,拟在我国溪洛渡等高拱坝中采用。在高水头、大流量作用下反拱水垫塘能否安全运用其稳定性是关键技术之一。分析了平底水垫塘和反拱水垫塘的稳定性原理,论证了反拱水垫塘底板具有超载能力强、稳定性高的优点,是高拱坝坝身泄洪消能的合理选择。

| Abstract: | The inverted arch plunge pool is a new type of energ -dissipation and riverbed-protection st ructure. It is planed to be applied in Xiluodu Hydropower Project with about 300m high arch dam. Its stability is a ke y technology which relates to whether it can be used in the condition of high wa ter head and large discharge. By making analysis of the stability principle on b oth inverted arch plunge pool and flat bottom one, the study results demonstrate that the inverted arch floor is little in anchoring quantity, high in its stability, and strong in its overload. Thus, it is an optimum shape and rational choi ce in considering discharge from high dam and water energy dissipation in the na rrow river valley. |
