摘　　要：以钢材、水泥、沥青及地材等短期材料为例,分析短期材料价格变动对公路施工造价的影响.研究结果显示,2021年的钢材、水泥、沥青及地材价格较2020年上涨,上涨率分别为19.1%、15.67%、11.08%和24.82%,分别占公路施工造价的2.47%、2.28%、0.31%和3.85%;短期钢材和水泥的价格指数变化区间分别为2.5%~9.6%和3%~10.9%,变化差分别为7.1%和7.9%,对公路施工造价的影响区间为0.0021%~0.0089%和0.0015%~0.0096%;4种材料价格上涨费用占公路施工造价的8.9%,在公路施工造价中占比较大,需加强前期公路施工造价管理.Taking short-term materials such as steel,cement,asphalt and flooring as examples,this paper analyzes the impact of short-term material price changes on highway construction costs.The research results show that the price of steel,cement,asphalt and flooring materials in 2021 increased compared with that in 2020,with the rising rates of 19.1%,15.67%,11.08%and 24.82%respectively,accounting for 2.47%,2.28%,0.31%and 3.85%of the highway construction cost.The change range of short-term steel and cement price index is 2.5%~9.6%and 3%~10.9%respectively,the difference of change is 7.1%and 7.9%respectively,and the impact range on highway engineering cost is 0.0021%~0.0089%and 0.0015%~0.0096%.The rising cost of four kinds of materials accounts for 8.9%of the highway construction cost,which is relatively large in the highway construction cost.It is necessary to strengthen the highway construction cost management in the early stage.
