摘　　要：大跨混凝土拱桥以其跨越能力强、刚度大、承载能力强的特点,近年在我国山区铁路中广泛应用。目前,我国尚未有统一的针对大跨拱桥的检查维修的相关规程及相关设备。文章以已建成的沪昆高速铁路北盘江特大桥为工程背景,针对大跨度混凝土拱桥后期运维的需要,介绍该桥的检查维修通道及针对该桥研发的一种新型的大跨混凝土拱圈检查车的设计。为同类大跨度拱桥的管养维护提供技术参考。In recent years,the long-span concrete archbridge has been widely used for railways in the mountainous areas in China because of strong span ability,strong stiffness and strong bearing capacity. At present,the unified relevant regulations and equipment for the inspection and maintenance of long-span arch bridge have not been made in our country. Based on the completed Beipan river bridge of Shanghai-Kunming passenger dedicated railway line,aiming at the inspection needs of long-span reinforced concrete arch bridge during the operation and maintenance period,the inspection lane and a new type of inspection vehicle for long-span concrete arch ring are presented,which can provide technical references for the maintenance of the same kind oflong-span arch bridges.
