考虑供水主管影响的公路拓宽方式选取研究

Study on Selection of Highway Widening Ways Considering Influence on Water Supply Pipe

合理的公路拓宽方式不仅能有效提高通行能力,满足急剧增长的交通量需求,还能节约工程造价、减少对现状的影响。结合实际公路拓宽项目,提出了项目需要考虑的四大影响因素:现状供水主管、拟建供水主管、拆迁、工程造价,并对这些影响因素进行了定量分析,然后采用多指标综合评价法对主要的拓宽方式进行了比选。通过定量化的分析结果,得出了老路拓宽方式的合理方案,为以后的研究和设计提供了一定参考。

A reasonable widening way of highway can not only effectively improve the traffic capacity and meet the rapidly increasing traffic demand,but also save the engineering construction cost and reduce the influence on the status quo.Based on the actual project,this paper puts forward four influential factors of the status quo of water supply pipe,the proposed water supply pipe,the demolition and the engineering construction costs to be considered in the projects,and quantitatively analyzes these influencing factors,and then uses the multi-index comprehensive evaluation method to compare and select the main widening ways.Through the quantitative analysis results,the reasonable scheme of old road widening way is obtained,which provides some references for the future study and design.
