文章以广西某通航桥梁为例,通过数值模拟分析该桥梁在设防船型撞击条件下的结构抗力、动力响应特征,并以此进行桥墩防撞能力验算及防撞策略分析。计算结果表明:在规划5000吨级内河船舶的碰撞作用下,桥墩桩基产生的轴拉力超过恒载轴力,... 文章以广西某通航桥梁为例,通过数值模拟分析该桥梁在设防船型撞击条件下的结构抗力、动力响应特征,并以此进行桥墩防撞能力验算及防撞策略分析。计算结果表明:在规划5000吨级内河船舶的碰撞作用下,桥墩桩基产生的轴拉力超过恒载轴力,桥墩原有最大撞击抗弯能力仅为需求值的1/10~1/3;设置主动分离式防撞墩及被动超高、偏航提醒系统可提升大桥防船撞能力,有效避免船撞事故引起的桥梁安全问题。 展开更多

The consequences of ship collisions with an oil rig, offshore installation or platform can be far more expensive in relation to safety, environment and costs of damage. The damage due to a single incident of an Oil Rig Collision can be catastrophic due to the number of people on board and the added risk of explosion. However, the existing rules and regulations of collisions prevention are insufficient. The purpose of this article is to critically evaluate the risk of ships collisions with offshore platforms and installations and therefore propose an international regulation for the preventions of this type of collisions. 展开更多
