摘要
抛投落距直接影响到四面六边透水框架体施工抛投定位精度和工程实施岸段的护岸效果,但目前尚没有四面六边透水框架体抛投落距的计算公式.为此,首先通过流动水体中四面六边透水框架体运动规律的理论分析,得出了其抛投落距计算的理论公式,然后通过水槽试验研究了四面六边透水框架体在不同流速和不同水深条件下的抛投落距,提出了四面六边透水框架体抛投落距计算的经验公式.
The throwing distance of the permeable frames of a tetrahedmn with six sides directly relates to the precision of the throwing positions and the effects of bank protection. However, there are still no equations for calculating the throwing distance of the permeable frames of a tetrahedron with six sides. Based on theoretical analysis of the motion law of the permeable frames of a tetrahedron with six sides in flowing water, a theoretical formula for calculating the throwing distance was developed. Through flume experiments, the throwing distances of the permeable frames of a tetrabedron with six sides with different velocities and water depths were determined, and a relevant empirical formula is proposed in this paper.
