山地城市新增快速通道设计

Brief Analysis on Design of New Fast Channel in Mountainous City

山地城市以其复杂的地形、多变的要素不同于平原城市。山地城市道路设计的复杂性和难度明显大于平原城市,尤以在特大型山地城市新增快速通道的设计难度为大。以重庆市重点工程——曾家岩北延伸穿越内环新增通道工程项目(以下简称“曾家岩项目”)为例,提出山地城市新增快速通道设计中应注意的问题。

A mountainous city is different from a plain city because of its complex topography and variable elements.The complicacy and difficulty in the design of roads in the mountainous cities are obviously larger than the plain cities,especially in the design of new fast channels in the super-large mountainous cities.Taking Zengjiayan North Extension Crossing Inner Ring New Channel Project-an major project in Chongqing as an example,the problems for attention in the design of new fast channel in mountainous city are put forward.
