摘要
重庆绕城高速公路互通立交众多,造成互通立交之间的间距较小,为使立交间距既满足最小间距要求又不影响绕城高速公路作用的发挥,笔者通过对绕城高速公路立交特征的分析,并根据JTGD20—2006《公路路线设计规范》对立交间距的规定,结合重庆和国内其他城市已建城市环线高速公路小间距立交设置的成功实例,对城市环线高速公路互通立交密度进行探讨,并提出城市环线上小间距立交对策措施的初步意见。
There are so many interchanges on the ring highways of Chongqing that the space between interchanges becomes smaller and smaller. In order to meet the requirements of minimum space between interchanges and enable the ring highway to be made full use of, the characteristics of interchanges on the ring highway are analyzed. According to the criterion of the interchange space in ＂Highway Route Design Specification＂ （JTG D20--2006）, the interchange density of Chongqing ring highway is discussed, with the combination of successful examples of small distance interchanges built in Chongqing and other cities. Finally, preliminary measures of small distance interchanges on the ring highway are proposed.
