上海内河跨航道桥梁防撞设施分析

Analysis of anti-collision facilities of bridge crossing inland waterway of Shanghai

针对上海内河跨航道桥梁水上防撞设施,对桥梁防撞体系、船撞力计算方法进行论述,结合内河跨航道桥梁自身特点和最新防撞理念,对适合内河跨航道桥梁的防撞方案和设施进行分析。结果表明:适合上海内河跨航道桥梁水上防撞的防撞设施主要有固定或浮式防撞装置和桩基防撞墩两种类型,若这两种类型防撞设施不具有施工条件,一般采用小规格缓冲材料对桥墩进行防护;对于与黄浦江直接连通的支流桥梁,除小规格缓冲材料,一般采用防护桩。

In view of anti-collision facilities of bridge crossing inland waterway of Shanghai,we discuss the anti-collision system and calculation method of ship collision force.Combining with the characteristics of bridge crossing inland waterway with the latest anti-collision concepts,we analyze the anti-collision scheme and facility which are adaptable to the bridge crossing inland waterway.The result shows that there are fixed or floating anti-collision facility and anti-collision pier which are suitable for the bridge crossing inland waterway.If the construction condition of the two types of anti-collision facilities is not available,small specification buffer material is always adopted to protect the bridge pier,and fender pile is also a selection in the bridges which connect the Huangpu River with tributary.
