摘要
分别通过对跨座式单轨与地铁、悬挂式单轨的对比,分析其优势和局限性,并通过跨座式单轨在国内外大中城市及小型城镇不同功能定位的分析明确其适用性。轨道梁的设计是跨座式单轨交通的关键技术,首先对比分析了不同材质和截面类型的简支体系轨道梁的特点。基于连续刚构体系轨道梁的特点并与简支体系对比,说明连续刚构体系轨道梁的优越性。连续刚构体系轨道梁改善了传统简支体系轨道梁跨径小、运能低、轮胎磨耗大、对支座和接缝养护维修工作量大、曲线半径设计受到限制等缺陷,具有广阔的应用前景。
Compared in the paper are the straddle monorail,the subway, and the suspension monoraiUwith their respective ad-vantages and limitations analyzed. Through analyzing the different functional grades of the straddle monorail in large, medium and small municipalities or towns both at home and abroad,the applicability of the straddle monorail is made clear. As the de-sign of the track beam is the key technique of the straddle-type monorail transportation, the characteristics of simply supported beams with different materials and section types are first compared and analyzed. Upon the analysis of the characteristics of the continu-ous rigid frame beam and the comparasion between the continuous rigid frame beam and the simply supported system, the advantages of the track beam of the continuous rigid frame beam are proved. Having overcomed the defects of the traditional simply supported beam system in being small in spanning width,low in transport capacity, large in tire wear,great in maintenance and repair work for bearings and joints,the limitations in the design of the curve radius and so on,the continuous rigid frame beam enjoys wide application prospect.
