三峡水库变动回水区泥沙问题物理摸拟的进展

The Advance in Physical Modelling of Sedimentation in the Fluctuating Backwater Region of Three Gorges Reservoir

本文重点介绍应用在研究三峡工程水库变动回水区的泥沙冲淤和河床演变问题中所采用的泥沙模型设计、试验技术以及模型沙的选择方法,建造汉江丹江口水库变动回水区油房沟河段泥沙模型,用1976年至1990年原型观测资料,复演全时段河道再造床过程的试验研究工作。本文可以看作是晚近中国在悬移质泥沙物理实体模型模拟技术方面新进展的总结。

This article addresses the model design method, test technique and selection of model sand employed in the research of suspended load for the Three Gorges Reservoir. Also, This paper describes in detail the model-prototype comparison test with the use of data collected in 1976-1990 at the existing Danjiangkou reservoir on the Hanjiang River to make sure of the reliability of those method and technique. This paper might be regarded as a summary of advances which appear in the techniques of physical modelling of reservoir suspended load in recent years in China.
