摘　　要：为指导气泡幕拦浑实践,采用理论推导,给出气泡幕拦浑所需单宽曝气量的计算公式,以及气泡幕开孔管径尺寸的计算方法,将新的计算公式和方法应用于宜春港樟树港区河西作业区综合码头的港池疏浚工程的气泡幕拦浑作业,并总结气泡幕拦浑施工工艺。结果表明:气泡幕具备良好的拦浑效果,但气泡幕拦浑最佳单宽曝气量小于理论值。总体来看,气泡幕装置结构简单、安装方便,拦浑效果良好,且不妨碍船舶正常通行,与防污帘组合使用阻拦悬沙扩散效果更佳。In order to guide the practical application of sediment interception using a bubble curtain,we use a theoretical derivation to provide calculation formulas for the required aeration rate per unit width and a method for calculating the diameter of the bubble curtain’s perforated pipe,apply these new calculation formulas and methods to the sediment interception operation for the harbor basin dredging of the comprehensive terminal project in the Hexi operation area of Zhangshu Port in Yichun Harbor,and summarize a construction process for the sediment interception with the bubble curtain.The results show that the bubble curtain has a good sediment interception effect,but the optimal aeration rate per unit width for sediment interception is lower than the theoretical value.Overall,the bubble curtain device has a simple structure,easy installation,good sediment interception effect,and does not hinder normal vessel passage.Combined with silt curtains to prevent the spread of suspended sediment,it works even better.
