自航耙吸式挖泥船泥土处理的方法很多,其中装舱溢流外抛是最常用的一种。每船装舱溢流时间的长短受船舶性能、操作水平、运距远近、挖掘土质、溢流效果等多种因素影响,其中决定因素则是综合挖泥效果最佳,经济效益做好。图一是理想状态下自航耙吸式挖泥船装舱溢流的施工过程曲线示意图。该图假设条件为抛泥运距10km,挖泥船轻载速度20km/h,挖泥船重载航速 Self-propelled suction hopper dredger soil handling many ways, of which loading overflow overflow is the most commonly used one. The length of overflow time for loading a ship is affected by many factors, such as the performance of the ship, the operation level, the distance of transportation, soil excavation and overflow effects. The decisive factor is that the comprehensive dredging effect is the best and the economic benefit is good. Figure 1 is an ideal curve of self-propelled suction hopper dredger hopper loading process curve. The figure assumes the conditions of throwing mud distance of 10km, dredger light load speed of 20km / h, dredger overloaded speed
