The invention relates to a method for evaluating the ship collision risk of an existing bridge pier, and the method comprises the following steps: collecting bridge pier information, channel information and ship information, and carrying out the classification of ships, and obtaining all types of ships; calculating the critical impact speed of each type of ship impacting the bridge pier according to the anti-impact force of the bridge pier; calculating the critical sailing speed of the ships of each category according to the critical impact speed, and further obtaining the number of the ships of which the sailing speed is greater than the critical sailing speed in each category; calculating the geometric collision probability of the ship and the bridge pier of each category; and calculating the bridge failure probability according to the number of ships of each category and the geometric collision probability. According to the method for evaluating the ship collision risk of the existing bridge pier, the complex risk probability evaluation work of the ship colliding with the bridge pier is refined into a plurality of independent risk probability evaluations and summing is carried out, the evaluation process is clear, the operability is high, and the working efficiency of evaluating the ship collision risk of the existing bridge pier is improved.

    本发明涉及一种既有桥墩船撞风险评估的方法,包括以下步骤:收集桥墩信息、航道信息及船舶信息并对船舶进行分类,得到各个类目的船舶;根据桥墩的抗撞力计算各个类目的船舶撞击桥墩的临界撞击速度;根据临界撞击速度计算各个类目的船舶的临界航行速度,进而得到各个类目中航行速度大于临界航行速度的船舶数;计算各个类目的船舶与桥墩的几何碰撞概率;根据各个类目的船舶数及几何碰撞概率计算桥梁失效概率。本既有桥墩船撞风险评估的方法通过把复杂的船舶撞击桥墩的风险概率评估工作细化为若干个独立风险概率评估并求和,评估流程明确,可操作性强,并提高了对既有桥墩船撞风险评估的工作效率。
