摘要
因公路选线的各种制约因素越来越多,平曲线在线形设计中所占的比例越来越大,合理的超高设计显得尤为重要。其超高旋转方式的选择、超高设计值的确定、超高过渡段长度设置的是否合理直接影响到行车的安全、平稳、舒适。对《公路路线设计规范》(JTG D20-2006)中有关超高设计方面的规定,提出自己的见解。
Because more and more restraining factors of road line selection and larger and larger proportion of horizontal curve in geometric design, reasonable superelevation design are very important. The selection of superelevation rotation mode, determination of superelevation design value and setup of length at superelevation transition section will directly influence the safety, stability and comfort of driving. The negotiation opinion is put forward for the stipulation in the relevant aspect of superelevation design of Design Specification for Highway Alignment （ JTG D20 - 2006）.
