摘　　要：通过实例介绍国内河道截流工程采用的方法和进展。其中戗堤截流，包括立堵、平堵和平立堵结合，以及单戗堤、双戗堤进占等。80年代以来，为了减少截流难度，多采用综合措施。此外，还介绍了长科院对葛洲坝等工程截流抛投块体的稳定研究，促进了抛石截流理论的发展。Methods and deve1opment adopted for river channel closure are presented with examples inChina, such asclosure dikes, incloding end - tipped closure, frontal dumping closure and their com binations,and closure with one or two banks,etc. Comprehensive measures have been mostly used in order to reduceclosure difficulty since 198O's. The stability study by changjiang Resesrch lnstitute Wuhan, and also presen-ted of dumped cubes for river closure of the Gezhouba projects,tec, which has promoted development of thetheory on river closure of dumped rockfills.
