用整体悬挑结构拓宽山区道路新技术

Widening Mountainous Highway with Integer Cantilevered Structures

本文针对陡峻山区道路拓宽工程,在分析比较目前常用道路拓宽方式的特点后,提出"一种用悬挑结构拓宽山区道路的方法",其设计理念是:杜绝深挖高填,在确认现已稳定路基范围内用整体浇筑的墙柱式挡墙形成路堤,以悬挑结构补足道路欠宽部分。本文对该方法的工作原理进行了分析,并将其成功应用于工程实践。工程实践表明,在高陡边坡条件下的道路拓宽中,本文方法较目前常用的道路拓宽方法既能简化工艺、降低造价、安全可靠,又能最大限度地保护自然生态环境。

A new method of Widening Mountainous Highway with Integer Cantilevered Structures is proposed for steep mountainous areas after comparative analysis of the current methods used to wide roads. The design idea is that widening the road with integral casting wallpill retaining wall, making full use of exiting stable roadbed. The work principle of the integer cantilevered structures is analyzed, and successfully used in engineering practice. According to the engineering practice, this method which is applied for Widening Mountainous Highway with high and steep slope is not only simple in construction, economic and on the safe side, but also protecting environment.
