【摘要】 “宽尾墩 +消力池”是 3 0年前由我国首先提出并发展起来的消能形式。在依托工程模型试验的基础上 ,通过大量点、面水流脉动荷载测试数据的综合分析 ,基本掌握了宽尾墩射流作用下消力池底板动水压力的规律性分布 ,提出了点、面脉动荷载系数确定方法和结果 ,不仅为工程消力池底板结构稳定计算提供了科学依据 ,而且也提高了该消能形式水流动力特性的认识。更多还原

【Abstract】 Tail-flaring pier + stilling pool " is an energy dissipation method first put forward by China 30 years ago. Based on model test results and the synthetic analysis of flow fluctuation load testing data for great quantity of points and areas, the distribution of hydrodynamic pressure on stilling pool base slab under jet flow from tail-flaring pier is generally drawn out, the selection principle and point, area fluctuation load factors are put forward, which not only provide a scientific basis for the Baise stilling pool base slab structural stability calculation, but also enrich our knowledge on the flow dynamic characteristics of this energy dissipation method.更多还原
