摘　　要：铺缆船用电缆埋设犁是用于海底电缆铺设的专用装备。在铺缆船拖绳提供的拖曳力作用下,电缆埋设犁在海底实现边挖沟边铺设电缆。电缆埋设犁在工作过程中,受力情况非常复杂。为了保持电缆埋设犁行进过程中能有效挖掘海底土壤和稳定性,需要对埋设犁工作过程中的整机受力情况及铺缆船的拖绳受力情况进行综合分析与研究。该文以某型深水埋设犁挖掘工况为实例,从埋设犁整机受力情况入手,对埋设犁整机受力和铺缆船拖曳力相互关系及影响进行分析,为合理选用拖绳和确定参数,更好地保证电缆埋设犁顺利进行水下挖沟铺缆作业提供理论依据。The subsea cable ploughs for the cable laying ships are the special equipment for subsea cable laying.Under the towing force provided by the tow line of the cable laying ship,the cable plough can operate cable laying while trenching on the seabed.The stress condition is very complex during the working process of the cable plough.It is necessary to comprehensively analyze and study the force acted on the whole machine and the force of the towing line of the cable playing ship during the operation of the burial plough,in order to maintain the effective excavation of the seabed soil and stability.A deep-water burial plough under excavation condition is examined to analyze the correlation between the force of the burial plough and the towing force of the cable laying ship starting from the forces of the whole burial plough.It can provide theoretical basis for the reasonable selection of the towing line and the parameter determination to ensure the success subsea trenching and the cable laying operation of the cable plough.
