摘要
本文提出的新型浮体闸突破了传统浮箱式闸门只能在静水中施工和运用的限制,易于安装和制作,便于浮运和维修。文中根据系统受力平衡原理,详细分析了浮体闸在静水和动水中的稳定性及其影响因素,推导出浮体闸的沉浮稳定性计算公式。同时根据移重法改进了测定浮体闸重心高度的计算公式,通过试验验证了计算公式的正确性。此外,根据浮体闸最不利运行工况反向力偶矩的测定,提出了浮体闸在动水中的沉浮稳定性条件,并提出了在动水中增加稳定性的措施。
A new type of floating sluice is proposed. The new sluice differs from the traditional floating sluice in structure. It has a floating tank in the lower part of the structure and a flat gate which can be lying down is installed in the upper deck of the sluice. The sluice not only can be installed and operated in still water but also in flowing water. The forces acting on the structure and the factors affecting the equilibrium are analyzed. The formula for stability calculation is established. The validity of the formula is verified by model test. The measures for improving the stability of this kind of sluice are suggested.
