前言葛洲坝水利枢纽的泥沙问题从1971年开展研究工作以来,经过许多单位的大力协作和科技人员的辛勤劳动,十年来,提出了大量科研成果,满足了工程设计、施工的要求,并推动了我国泥沙学科的进展。水利枢纽的泥沙问题一般由以下三个因素确定,即河流的来水、来沙和河床边界特性,枢纽的类型与规模以及枢纽的任务。长江水量大、含沙量小,但长江泥沙包括沙、 Preface Gezhouba Hydropower Project Sediment Problem Since 1971, after carrying out research work, after many units of strong collaboration and scientific and technical personnel work hard over the past decade, put forward a large number of scientific research to meet the engineering design and construction requirements and promote the The development of sediment in China. Sediment problems in a water control project are generally determined by three factors, namely, the incoming water, incoming sand and riverbed boundary characteristics, the type and size of the hub, and the tasks of the hub. The Yangtze River has a large amount of water and a small amount of sediment, but the sediment of the Yangtze River includes sand,
