摘要
本文通过长江口航道淤泥的室内波浪试验研究,认为影响波长变化的主要因素有相对泥床厚度、泥床含沙浓度及相对(传播距离)波长等。在本试验范围内,波浪在泥床上传播时的波长变化一般在±5%以内;但在相对泥床厚度、泥床含沙浓度及相对(传播距离)波长均较大时,波浪被急剧衰减,波长也随之迅速减小。
Through tests that were conducted in a flume by using silt from the navigation channel of the Yangtze river mouth, the paper shows that the main affective factors of wave length are relative silt bed depth (D,/D),volume ratio of silt content in the bed (Sr) and relative wave length (L/l), etc.
In this experiment, change of wave length with wave flume propagating on the silt bed is mostly within ±5 %, but wave length will also promptly decrease along when depth of the relative silt bed, volume ration of silt content and relative wave length are all quite large.
