摘要
作为互通式立交基本单元的匝道,其设计合理与否将直接影响立体交叉的功能、行车安全和工程投资等。阐述了匝道变速车道设计、匝道线形指标检验及端部竖向设计等技术性问题,指出了在互通式立交匝道设计中需要考虑的主要因素。
The reasonable design of the ramp as a basic unit of interchange will directly affect the function,traffic safety and engineering investment of the interchange. The article sets forth the design of ramp speed-change lane, the inspection of ramp alignment index and the vertical design of end, and points out the main factors required to consider in the design of interchange ramp.
