摘　　要：针对尼日利亚首都阿布贾城铁的小半径曲线地段和大坡度地段等特点,从经济的角度初步选定拟使用的桥梁架设设备,并通过对桥梁架设设备在最不利条件下的施工工况进行理论分析,检算上述设备选型的技术可行性。同时在拟定设备的前提下,验证施工过程中桥梁运输和架设设备在小半径曲线地段和大坡度地段通行的技术可行性,最终确定了拟使用的桥梁架设设备在阿布贾城铁施工中应用的可行性,也为国铁成熟的铁路架梁设备和经验在未来城市轨道交通的规划设计和建设中的应用提供参考和借鉴。According to the characteristics of sharp curve section and large slope section of Abuja Rail Mass Transit in the capital of Nigeria,economic suitability was the preliminary consideration of the selected proposed machine and through theoretical analysis of beam launching machine under the most unfavorable construction conditions,the technical feasibility of the selected proposed machine was confirmed.At the same time,the technical feasibility of the proposed beam launching or transportation machine moving in sharp curve section and large slope section during construction was studied.Finally,the feasibility of the application of the proposed beam launching machine in the construction of Abuja Rail Mass Transit was determined.The railway beam launching machine and experience completed in national railway will provide reference for the planning,design and construction of urban rail transit in the future.
