基于造价的路线方案优化要点及在连贺高速上的应用

Key Points of Route Scheme Optimization Based on Cost and Its Application inLianshan-Hezhou Expressway

我国西南部山区山岭连绵庞大,地形复杂,高速公路桥隧规模普遍偏大,工程造价较高。本文结合广西连山至贺州公路的设计经验,对山区高速公路在设计阶段从总体路线角度优化降低工程造价的方法进行了研究和总结。

The mountains in southwest China are large and complex.The scale of highway bridges and tunnels is generally large and the project cost is high.Based on the design experience of Lianshan-Hezhou highway in Guangxi,this paper studies and summarizes the methods of optimizing and reducing project cost from the perspective of overall route in the design stage of mountainous highway.
