一、项目概况浙江舟山大陆连岛工程金塘大桥全长26.54 km,其中跨海桥长18.27 km。防撞设施拟采用高架走锚消能式拦阻船舶系统。重力锚走锚时的阻力与其重力成一定关系,走锚距离越远,其消耗的动能越多,因此可根据设防船舶吨位、船速、流速、风速等具体参数,合理确定防撞系统重力锚的大小和走锚距离。为了验证和优化结构设计,拟在西航道两侧非通航孔桥建设试验段并开展走锚消能测试与实船拦 I. Project Overview The Jintang Bridge in Zhoushan, mainland China with a total length of 26.54 km, of which the bridge spanning 18.27 km. Anti-collision facilities to be used overhead walking anchored energy-saving ship system. The resistance of gravitational anchor to go down the anchor is related to its gravity. The farther away the anchor is, the more kinetic energy it consumes. Therefore, according to the specific parameters such as tonnage, speed, flow velocity and wind speed of fortification, the gravity anchor The size and walking distance. In order to verify and optimize the structural design, it is proposed to construct the test section of non-navigable bridge on both sides of the West Channel and to carry out the test of energy dissipation by anchors and real ships
