该文针对大型桥梁防止大吨位船舶撞击的设施这一国际难题进行了研究。按照柔性消能防撞的模式成功研制出了抵抗5万t级船舶撞击的防撞设施,而且造价较低。该设施的成功实施成为国际首创。在研制过程中,还创造性地提出了“小撞不坏、中撞可修、大撞不倒”的三级防撞设计原则。 This paper studies the international problem of the facilities for preventing large-tonnage ships from colliding with large bridges. In accordance with the pattern of flexible energy dissipation crash successfully developed a collision resistant to 50000 t-class collision impact facilities, and lower cost. The successful implementation of this facility has become an international initiative. In the development process, but also creatively put forward the “collision is not bad, hit in the repair, crash does not fall,” the three anti-collision design principles.
