高速公路跨越蓄滞洪区段路线方案比选优化

Comparison and Optimization of Route Scheme for Expressway Crossing Flood Storage Area

以某高速公路为例,对跨越蓄滞洪区段路线方案进行比选优化。结果表明,为确保路线合理,应梳理项目所在地的区域特点和制约因素,进而明确设计思路及原则,在满足项目要求的前提下,综合标准、地形、地质、安全、造价等选线方式,提出多方案进行技术经济指标对比,择优选定推荐方案,以提升方案质量,降低工程投资,减少环境破坏,提高整体运营效益。

Taking an expressway as an example,this paper compares and optimizes the route scheme crossing the flood storage area.The results show that,in order to ensure the reasonable route,the regional characteristics and constraints of the project site should be sorted out,and then the design ideas and principles should be clarified.On the premise of meeting the project requirements,the route selection methods such as standard,terrain,geology,safety and cost should be comprehensively analyze,multiple schemes should be proposed to compare the technical and economic indicators.The recommended schemes should be selected to improve the quality of the scheme and reduce the project investment.Then the environmental damage would be reduced and overall operational efficiency would be improved.
