13新建煤运通道设计荷载标准及相关参数研究研究分析国内外重载铁路技术标准、重载铁路牵引试验、测试报告、国内已有的科研成果等技术资料,重点考察运营重载列车模式与荷载标准的关系。按照划分若干等级的思路研究确定荷载轴重等级,理论计算后综合分析不同轴重等级对新建煤运通道桥梁结构的影响。利用已有相关试验数据,通过理论计算研究确定配套的设计动力系数、离心力系数、横向
13 Research on Design Load Standards and Related Parameters for New Coal Transportation Corridor Analyzed technical standards of heavy-haul railway at home and abroad, traction test of heavy haul railways, test reports and existing scientific research achievements in China, with a focus on the operation of heavy-haul train modes and loads Standard relationship. According to the idea of classifying certain grades, the grade of load axle load is researched and determined. After theoretical calculation, the influence of different axle load grades on the bridge structure of new coal transportation corridor is comprehensively analyzed. Using the existing relevant experimental data, through the theoretical calculation and study to determine the supporting design dynamic coefficient, centrifugal force coefficient, horizontal
