摘要

近20 多年来，中国钢管混凝土拱桥和以钢管混凝土为骨架的混凝土拱桥获得大发展，跨径增大很快，在桥梁发展史上罕见。高速公路和高速铁路的大规模建设为大跨径拱桥的发展提供了需求，设计及施工技术的进步为修建大跨径拱桥提供了可能。作为这段历史的参与者，我们通过本文来介绍中国钢管混凝土拱桥和以钢管混凝土为劲性骨架的混凝土拱桥的发展状况及主要创新技术，内容主要包括钢管混凝土拱桥关键建设技术，如钢管拱桁设计、制造与安装，管内混凝土制备与灌注等技术，以世界最大跨度钢管混凝土拱桥——合江长江一桥为工程实例进行了详细介绍；以及劲性骨架混凝土拱桥的主要建设技术，如斜拉扣挂悬拼施工、斜拉扣索调载、拱肋外包混凝土浇注等，并对广西邕宁邕江大桥和云桂铁路南盘江特大桥两个工程实例进行了介绍。中国钢管混凝土拱桥取得了同类桥型世界领先的地位，随着关键技术的持续创新，将成为推动拱桥发展突破的新领军者。
