山区高速公路桥梁造价分析

Analysis of Construction Cost of Expressway Bridge in Mountain Region

交通部示范项目广梧高速公路是典型的山区高速公路,沿线地形、地质条件均十分复杂,构造物多,技术难度大,桥梁设计合理与否对整条公路的造价影响较大。该文旨在通过具体数据,在桥型方案、上部构造、下部构造和基础方面提出一些控制桥梁造价的思路。

Guangwu Expressway, a demonstrating project by the Ministry of Communications, is a typical expressway in mountain region. The topographic and geological conditions along the line are all much complicated, and there are many structures and the technical difficulty is large. Whether or not the bridge design is reasonable has the lager influence on the whole expressway. The article puts forward some thinking to control the bridge construction cost from the aspects of the bridge type scheme, superstructure, substructure and foundation on the detail data.
