风电机组设备重量大、叶片尺寸长，对运输道路有特殊要求，属于特种设备运输．文中针对目前国内大型山地风电场道路设计无规范可依的现状，系统调查了影响道路纵断面设计的叶片运输车辆相关指标． 从满足车辆在竖曲线上缓和冲击、行驶时间不过短、叶片甩尾悬空部分不刮蹭地面和半挂车俯仰角限制 4 个方面，研究了竖曲线最小半径和长度指标，得出了不同约束条件下的凹形竖曲线和凸形竖曲线最小半径、长度计算模型．最后通过计算分析，给出不同设计速度和坡差范围下竖曲线最小半径和长度技术指标的推荐值． 研究成果可供风机道路设计及建设参考，也可用于风机运输道路相关标准、规范的制定．

As the wind power equipment is heavy and its blades are long，it requires a special highway to transport，which belongs to special equipment transportation． As there is no specification for the highway alignment design of large-scale wind farms in the mountainous areas in China，the relevant indexes of large blade transportation vehicles，which influence the highway profile design，are systematically investigated in this paper． From the four aspects of mitigating the impact in the vertical curve of vehicles，ensuring an adequately long travel time，keeping the blade tail from scraping the ground and restricting the pitch angle，the minimum radius and length of vertical curves are analyzed，and the models to calculate the minimum radii and lengths of concave and convex vertical curves are constructed under different constraint conditions． Finally，the minimum radii and lengths of vertical curves are recommended for the large aerogenerator transportation with various design speeds and scopes of algebraic difference in grades． The results can provide guidance for the highway design and construction of the aerogenerator transportation，and can also be used to formulate the standards relevant to the aerogenerator transportation highway．
