摘要
絮凝现象是河口海岸细颗粒粘性泥沙研究的关键问题,它影响到泥沙运动的基本规律乃至河口海岸地理或环境的演变?由于问题的复杂性,目前对于粘性泥沙絮凝机理?絮凝影响因素及絮团沉降规律等还不是十分清楚?本文就近年来国内外对细颗粒泥沙絮凝现象,特别是絮团特性的研究进行了系统的总结,评价了部分研究成果,指出了需要进一步研究的问题?
Aggregation phenomena are key problems of researches on cohesive sediments in estuaries and on coasts because they affect the basic transport properties of sediments and even morphological and environmental evolution. The present understanding on the aggregation mechanism, the influence factors on the aggregation and the floc settling is still not very clear due to the complexity of the aggregation. The recent researches on the aggregation phenomena of fine-grained cohesive sediments, the properties of flocs in particular, are reviewed and evaluated. The problems to be studied are pointed out.
