| 摘 要： | 结合我国相关公路路线设计规范以及湖南省高速公路设计与管理实践，对高速公路中央分隔带弯道路段横净距进行计算分析，结果表明，若按照现有路线设计规范进行最小平曲线设计，高速公路局部弯道路段中央分隔带横净距不足以满足停车视距。然后，针对这一问题，综合考虑经济可行性和技术可行性，笔者提出了若干工程对策，为高速公路中央分隔带设计和运营管理提供参考。

| Abstract: | Based on road design standard and the design and management practice of Hunan high- ways, the lateral clear distance of curve at the median is calculated and analyzed, the result shows that the minimal curve radius of present specification cant assure the stopping sight distance at the highway medi- an. Then on the base of economic efficiency and Technical Feasibility, several engineering solutions are put forward for highway median design and operation management departments＂ inference. |
