摘　　要：以孟加拉宽轨铁路为例,按照中国先进、成熟的理论规范,推导时速120 km/h、轨距为1 676 mm的宽轨铁路最小半径,并将孟加拉手册中各计算参数与国内规范做对比,研究其合理性。Taking Bangladesh wide rail as an example, according to China＇ s advanced and mature theoretical norms, the mininmnl radius of a wide rail line with a track speed of 120 km/h and a track length of 1 676 mm is derived. The calculation parameters in the bangladeshi manual are compared with the domestic norms to study its rationality.

关 键 词：宽轨铁路 最小曲线半径 外轨超高
