Abstract: Nowadays the computation theory of continuous rib arch bridge in consideration of horizontal dis-tribation of load is not researched in considerable detail by engineers and scholars. Basell on the designof Jinglan Bridge in Liuzhou, this paper puts forward a computation method of continuous rib archbridge in consideration of horizontal distribution of load.The mothed is considerably simple and useful.

Key words: continuous rib arch bridge, horizontal distribution of load, bridge pier practical computation

摘要： 肋拱桥上部结构的设计需考虑单片肋的荷载横向分布系数，对于多跨连续肋拱桥如何计及每片肋的荷载横向分布系数并同时考虑桥墩参与共同变形、受力，这是一个较为复杂的问题，目前我国在设计多路连续肋拱桥时对这一课题还未进行详细的探讨、研究，本文以广西柳州静兰大桥为例提出了考虑活载横向分布时的多跨连续肋拱桥实用计算方法，该方法简单实用，易于为设计单位掌握。
