摘要
利用水槽试验结合工程现场观测对不同条件下单颗粒及混合石料的漂移、分选、抗冲等情况进行了对比 ,提出了较好的抛投方法及既有利于海塘稳定又节约投资的护底形式 ,取得了巨大的社会效益和经济效益 ;同时导得动水中单颗粒抛石落距的计算公式及船抛石料床面分布面积与船体开口面积、石料中值粒径、水流佛汝德数等之间的经验关系 ,可供进一步深入的理论研究和工程施工参考运用。
After studying the characteristics of drifting, classification, erosion resisting of rock riprap by combining flume experiment and field measurement, this paper presents a better way of rock riprap and a type of protecting the riverbed which can not only improve the stabilization of the seawall, but also save the investments of the project. Great social and economic benefits are gained. At the same time, the drift distance formula and the empirical correlation between the distribution area of rock riprap and the ship opening area, medium diameter of rock, the Froude number of flow, etc are deduced, it can be used in theoretical research and engineering practice for reference.
