摘　　要：绞吸挖泥船作业时绕定位桩旋转,旋转角度确定了挖泥船的挖泥宽度。在恶劣条件下,由于外部载荷的作用和绞车能力的限制,该角度将会减小。对在急流航段作业的绞吸挖泥船的环境载荷和不同设备配备下的作业能力进行了计算分析,并总结了规律,为绞吸挖泥船初步设计时的设备选取、作业环境条件的确定提供了方法。A cutter suction dredger moves around the spud during operation, and the cut width is decided by the swing an- gle, which would he reduced in severe environment by the effects of external loads and the restriction of winch＇s capacity. Computation and analysis for environment load and its effects on capability is carried out for a cutter suction dredger operating in rapid section of Yangtze River, and methods are proposed for determination of operating environment and equipment capa- bility in the preliminary design stage.
