摘　　要：对于水下闸门,为了保障水闸和船舶的通行安全,需要设计水上安全设施。拦阻网主索的设计计算是此类工程的难点和重点。以苏州河河口水闸水上拦阻网为例,利用动量原理,建立船舶的运动微分方程,运用数值计算方法,得到船舶冲程和拦阻时间,并分析船舶行程和速度随时间的变化规律,研究冲程和拦阻时间与主索拉力的关系,得到一些有益的结论。In order to protect sluice and the traffic safety of ships, the design of water security facilities are needed for underwater sluice. The design and calculation of arresting net are the difficult and focal point of this kind of project. Motion differential equation of ship was built with momentum principle by taking Suzhou river an example, and the length of stroke of the ship and arresting time were obtained by using numerical method, and the regularity of the length of travel and velocity of ship changing with time were analyzed, the relationships of length of travel and arresting time with pulling force of main rope were studied and some benificial conclusion were made.
