河绠是五十年代从苏联引入的一种木材水运收漂工程。由于我国的流送河道具有流速高、水深变幅大的特点,苏联的河绠受力计算方法及其提供的数据不能满足在我国流送河道上进行河绠工程设计的要求。笔者以原林业部中南林业设计院水工试验研究室进行的河绠受力计算方法水工模型试验研究资料为基础,从河绠水工模型试验理论和方法的角度,分析苏联中央木材水运科学研究所提供的两种河绠受力计算方法的特点和适应性,并对河绠受力的水力学本质提出新的认识。
Hehuang is a kind of timber water transportation and bleaching project introduced from the Soviet Union in the 1950s. Because of the characteristics of high flow velocity and large water depth in China, the calculation method of the river’s force in the Soviet Union and the data provided by it can not meet the requirements of the design of the river waterway in China. Based on the experimental data of the hydraulic model test of the force calculation method of the river shoals conducted by the Central South Forestry Design and Research Institute of the Ministry of Forestry of Central South Forestry Design and Research Institute, this paper analyzes the theories and methods of hydraulic model tests of the river shores, The institute provided the characteristics and adaptability of two methods for calculating the force of river rips, and put forward a new understanding of the hydraulics essence of river rips.
