摘要:
随着跨江跨海桥梁与船舶通航数量日益曾多,船桥碰撞的概率也日益增大,所以亟须提出桥梁防船撞设计方案。针对既有椒江大桥水中通航孔桥墩,首先通过规范和Midas/Civil软件计算出桥墩结构的自身抗撞能力; 基于非线性动力软件ANSYS/LS-DYNA建立有限元模型计算得出典型桥墩遭受3 000 t级船舶正向和侧向撞击工况下的撞击力; 通过比较桥墩自身抗力与船舶撞击力,提出了一种隔离式防撞墩与自浮式消能圈相组合的新型桥梁防船撞方案,然后对单独设置隔离式防撞墩和设置隔离墩与自浮结构组合防撞系统两种工况进行计算。结果表明:桥墩自身抗力为14.40 MN,而受船舶撞击所产生的最大撞击力为24.38 MN; 设置组合防撞系统后,桥墩墩身所受的撞击力为0,隔离式防撞墩与自浮式消能圈有效保护了桥墩结构,且减小了船舶损伤。
Abstract:
With the increasing number of bridges and ships navigating across rivers and seas, the probability of collision between ships and bridges is also increasing. Therefore, it is urgent to propose a design scheme for piers. For the pier of the navigable hole in the Jiaojiang Bridge, the self-collision capacity of the pier structure was first calculated by specification and Midas/Civil software. A nonlinear dynamic finite element model was established to calculate the impact force of a typical pier subjected to a 3 000 t ship’s forward and side impact using ANSYS/LS-DYNA software. By comparing the self-resistance of the pier with the ship’s impact force, a new type of bridge anti-collision scheme was proposed, which consisted of an independent pier and a floating composite structure. Two working conditions of separately setting the anti-collision pier and the setting of the anti-collision pier and the anti-collision ring was calculated. Results showed that the self-resistance of the pier was 14.40 MN, and the maximum impact force generated by the ship’s impact was 24.38 MN. After the anti-ship collision prevention facilities were installed, the impact force of the pier body was reduced to 0, isolated anti-collision pier and its self-floating anti-collision system effectively protected the bridge pier structure and reduced the ship damage.
