【摘要】 随着全国城市轨道交通的快速发展,已出现了钢轮钢轨、跨座式单轨、有轨电车及胶轮路轨等多元化轨道交通制式。以重庆轨道交通3号线一期及南延伸为例,通过对跨座式单轨的核心技术——轨道梁和道岔自主研发及工程技术创新点的介绍,倡导全国各地因城设计,以重庆市跨座式单轨交通示范性工程为样板,走出一条"引进—消化—再研发"的创新之路,自主创新,驱动多层次、多制式的轨道交通发展。更多还原

【Abstract】 With the rapid development of urban rail transit in China,there have been many kinds of rail transit systems such as steel wheel on steel rail,straddle-type monorail,tram and rubber tire on roll way.Taking the first phase and south extension projects of Chongqing Rail Transit Line 3 as examples,the core technologies of straddle type monorail are introduced including the independent development and technical innovations of track beam and switch.It is advocated that the development of rail transit should combine with every city’s characteristics,and lead a technical innovation road of"introduction,digestion and re-development".更多还原
