摘要： 随着社会的发展与经济的进步，重载运输企业需求激增，大件运输车辆的通过性尤为 重要，为了保证公路大件运输的安全性。以大件运输车辆作为研究对象，按照车辆的经典组 合类型，对牵引车+低平板半挂车组合建立横断面、空间通过性的评价模型。通过对车辆在匝 道上的运行状态进行理论化的计算分析得到可通过的转弯宽度、理论扫空宽度，借助线路的 工程技术指标对车辆的匝道安全性和通过性进行详细的评价。经过评价体系的分析有助于公 路大件运输车辆路径的选择，提高运输经济效益。通过江苏丰洋公司的运输案例，进行运输 前的匝道通过性理论计算，保证通过性的条件下选择最优的公路运输路径，提高整体的运输 效率。

Abstract: With societal development and economic progress, demand for heavy-load transportation services has surged, making the passability of oversized transport vehicles particularly critical to ensure highway safety during such operations. Taking oversized transport vehicles as the research subject, an evaluation model for cross-sectional and spatial passability is established for the tractor-low-bed semi-trailer combination based on classic vehicle configurations. Theoretical computational analysis of the vehicle's operational state on ramps yields passable turning width and theoretical clearance width. Utilizing route engineering technical indicators, a detailed assessment of ramp safety and passability for the vehicle is conducted. Analysis through this evaluation system aids in selecting optimal routes for oversized transport vehicles, enhancing transportation efficiency and With societal development and economic progress, demand for heavy-load transportation services has surged, making the passability of oversized transport vehicles particularly critical to ensure highway safety during such operations.
