上海市轨道交通明珠线全长62 km,规划南起闵行,北至宝山。在全长25 km的明珠线一期工程中,高架线路为21.5 km,地面线路为3.5 km,沿线设19个车站,除起点漕河泾站及石龙路站、上海火车站为地面站外,其余16个都是高架车站。 为减少噪声,设计师们三管齐下。首先从轨道结构上着手,在全线铺设混凝土整体道床,上面铺设60kg/m的钢轨,跨区间焊接成2000 m以上的超长无缝线路,既减少轮轨冲击和噪声,又保持列车平稳运行;此外在钢轨扣件中插加30 mm厚的橡胶垫层,在半径较小弯道的钢轨侧面涂油,以减轻轮轨之间的直接挤压和摩擦。其次在机车车辆的制造上,设计使用无声的空气制动装置,在车轮旁安装挡音的垂裙。第三在隔
The total length of the Shanghai Metro Pearl Line is 62 km. It is planned to start from Minhang in the south and to Baoshan in the north. In the first phase project of the Pearl Line with a total length of 25 km, the overhead line is 21.5 km and the ground line is 3.5 km. There are 19 stations along the line. Except for the starting points of Caohejing Station and Shilong Road Station, Shanghai Railway Station is the ground station, The remaining 16 are elevated stations. To reduce noise, designers have three pronged. First of all, starting from the track structure, laying a concrete monolithic ballast on the whole line, the laying of 60kg / m rails, welding across the interval into more than 2000m long seamless lines, both to reduce the wheel and rail impact and noise, and keep the train running smoothly In addition, a 30 mm thick rubber cushion was inserted into the rail fasteners to lubricate the rail sides of the smaller radius to reduce direct compression and friction between the wheel rails. Second, in the manufacture of rolling stock, the design uses a silent air brake device, installed in the wheel next to the sound of the skirt. Third in the interval
