波浪作用下珊瑚砂的起动研究

The study on the sediment starting of coral sands under the action of the wave

本文概述珊瑚砂的物理特性,测量到珊瑚砂起动的起动波高以及对应的近底流速。总结了理论研究的两种基本方法,依托得到的数据并结合泥沙起动的Shields曲线得到适用于珊瑚砂起动的Shields曲线,对今后的珊瑚砂研究具有一定的参考意义。

The paper firstly outlined the physical characteristics of coral sands,then it observed the height of the wave velocity of coral sands＇ sediment starting and the corresponding near bottom speed of flow.The study concluded two basic measures of theoretical research according to obtained data as well as combining the Shields curve of sediment starting, and then got the Shields curve that was applicable to the sediment starting of coral sand,which provided a certain reference for further study on coral sand.
