| 摘 要： | 对中日两国在城市高架道路方面的设计规范进行比较,分析日本在用地条件极端困难的情况下建设城市高架道路所采取的各种有别于公路桥梁的方法,探寻在规划设计方面趋利避害的方法。提出保证桥上建筑限界、增加路缘带宽度、压缩护栏结构尺寸等思路,并对桥梁最大纵坡和匝道最小宽度等问题进行探讨。

| Abstract: | By comparing the design specifications of urban elevated roads between China and Japan,this paper analyzes various methods different from the highway bridges adopted by Japan to construct urban elevated roads under extremely difficult conditions of land use,and explores the methods of seeking benefits and avoiding disadvantages in planning and design.This paper puts forward some ideas of guaranteeing the building limit on bridge,increasing the width of marginal strip and reducing the size of guardrail structure,and discusses the maximum longitudinal slope of bridge and the minimum width of ramp. |
