摘要
肯尼亚内罗毕快速路项目是“一带一路”重要工程之一,是东非地区首次采用预制装配桥墩设计与施工的示范项目。结合项目的建设条件和特点,总结适用于当地城市高架桥预制装配桥墩的设计思路与要点,对构件连接方式进行研究和比选,同时对预制装配桥墩和传统现浇桥墩工程经济效益进行对比。对后续东非地区城市高架桥的建设具有参考意义。
Nairobi Expressway Project in Kenya is one of the important projects of the Belt and Road,and it is the first demonstration project in East Africa to adopt prefabricated pier design and construction.Based on the construction conditions and characteristics of the project,summarize the design ideas and key points suitable for prefabricated and assembled bridge piers of local urban elevated bridges,study and compare the connection methods of components,and compare the economic benefits of prefabricated and assembled bridge piers with traditional cast-in-place bridge piers.It has reference significance for the construction of urban elevated bridges in the East African region in the future.
