三峡工程泥沙研究的进展

本文回顾了1983年以来长江科学院开展三峡工程泥沙问题研究,通过原型观测调查、数学模型计算和泥沙模型试验相结合的途径所取得的主要成果。这些成果包括水库长期使用、水库变动回水区泥沙淤积、坝区泥沙冲淤,以及坝下游冲刷问题。

Advances in Sediment Research of Three Gorges Project

This paper reviews the results of study performed by Yangtze River Scientific Research Institute on the sediment problems of Three Gorges Project on the Yangtze River. Those results were obtained through field data analysis, theoretic analysis and model study during the past eight years. Results relate mainly to: 1. permanent use of reservoir; 2. sedimentation in fluctuating backwater region; 3. sedimentation in the neighborhood of dam; 4. degradation in the downstream reach.
