摘　　要：针对重大件公路运输中的主要影响因素最小圆曲线半径及加宽值的计算问题进行了分析与研究,提出采用坐标法进行最小圆曲线半径及加宽值的计算方法,推导了计算公式,并结合工程实践进行了实例计算和运用。其研究结果对类似项目重大件运输公路的规划、设计和建设工作具有积极的意义和实用价值,对《公路路线设计规范》的修订也具有参考价值。The heavy cargo transportation of national key projects is a common problem in highway transportation. Road adaptability and road passing capacity should often be analyzed and calculated when the above problem occurs. The calcu-lation of minimum curve radius and widening value which are the main influence factors in heavy cargo transportation was analyzed in this paper, the coordinate method in the calculation of minimum curve radius and widening value was also proposed in the paper. At the same time, the computing formulas which was applied in highway engineering practice was derived in this paper. The research resuhs have positive significance and practical value in the planning, design and con-struction of highways. It also has reference value in the revision of specification for highway alignment design.
