Method for arresting large-tonnage ships

The invention discloses a method for arresting large-tonnage ships, which is characterized in that at least two fixed piers are arranged above water, at least a constant resistance device is arranged between the two adjacent fixed piers, then an arresting gear with ultimate tension less than or equal to the horizontal strike resistant force of the fixed piers is taken, one end of the constant resistance device is connected with the arresting gear and the other end thereof is connected with the fixed piers, finally a plurality of spaced buoys are arranged between the two adjacent fixed piers and the arresting gear is fixedly connected with the upper parts of the buoys. The method has the following advantages: the large-tonnage ships at higher speed can be effectively arrested, the fixed piers and the arresting gear can be prevented from damage or breakage due to excessive stress, the method ensures the effectiveness of arresting and is suitable for extensively protecting the large-tonnage ships with immense kinetic energy from striking the bridges; in addition, the arresting system used in the method has long life cycle, is convenient to replace and maintain and has relatively low cost, thus being suitable for engineering.
