基于全寿命周期成本理论的山区高速公路路线方案比选

Mountainous Highway Route Scheme Comparison based on the Theory of Whole Life Cycle Cost

修建山区高速公路规模大、技术要求高、施工环境复杂、投资风险大。此文引入全寿命周期成本理论,针对某山区高速公路某区段在可行性研究阶段提出的A、B两种线路走向方案,进行全寿命周期成本影响因素分析,全寿命周期(30年分析期)费用计算、比较与分析,结果表明,A方案优于B方案,故采用A方案。

The construction of mountainous highway has big scale, high technical requirements and complex construction environment, big investment risk. This article introduced the whole life cycle cost theory to analyze the influencing factors of the whole life cycle cost aiming at the A ,B route schemes proposed in the feasibility study phase of a certain mountainous highway section. The calculation,comparison and analysis of the whole life cycle analysis （30 years） cost show that the A scheme is superior to B scheme, and the A scheme is adopted.
