摘要
长江下游某码头引桥受失控船舶撞击出现严重损伤,根据引桥排架横梁、桩基以及联接处的损伤类型、损伤程度和损伤位置,分析对结构安全的影响,提出了补桩或粘型钢综合加固两种方案,经技术经济分析推荐粘型钢加固方案。
An approach bridge of a high piled port in the lower reaches of the Yangtze River was hit by a ship and is seriously damaged.Based on the damage type,damage degree and damage location of the approach bridge scaffold beam,pile foundation,the influence of damage on structure safety is analyzed,then two schemes of reinforcing pile or bonding steel are put forward.Through technical and economic analysis,the reinforcement scheme of stick steel is recommended.
