码头引桥受船舶撞击的事故屡有发生。受撞钢管桩挠曲变形的确定,是事故技术鉴定的重要内容之一。本文介绍了宁波北仑码头引桥铜管桩受船舶撞击后,用测斜法在水下量测其挠曲变形的原理、仪器、方法、结果及误差估计。实践证明,本文方法对于风浪很大、潮汐变化剧烈和水下能见度极低的海域是有效的,对于其他水域的受撞钢管斜桩的水下挠曲变形的量测也具有普遍意义。
Pier bridge by ship collision accidents have occurred. Confirmation of the deflection of the steel pipe pile subjected to impact is one of the important contents of the technical identification of the accident. This paper introduces the principles, instruments, methods, results and error estimation of the Beilun quay bridge copper pipe pile subjected to the ship collision by using the incline method to measure its deflection under water. Practice has proved that this method is effective for large sea waves, intense tidal changes and extremely low visibility underwater. It is also of general significance for the underwater flexural deformation measurement of inclined steel piles struck by other waters.
