高速公路工程造价测算研究

Research on Project Cost Calculation of Expressway

通过统计分析平原、丘陵、山区三个片区多条高速公路造价数据,运用多元线性回归分析法、方差分析法等方法,将高速公路分为主线工程、隧道、互通服务区三个部分进行工程造价测算,建立高速公路带有片区特征的高速公路工程造价测算模型。研究结果表明:所提出的高速公路工程造价测算模型拟合度高,绝大多数测算误差控制在±10%以内,测算精度与工程实际数据吻合度较好,可作为高速公路投资决策的重要参考依据。

This paper uses the multiple linear regression analysis method,variance analysis and other modern mathematical theory methods through statistical analysis of the cost data of multiple expressways in three areas,namely plain,hill and mountain area,proposes a new method to calculate the project cost by dividing the expressway into three parts:the main line project,the tunnel and the interchange service area,establishes the expressway project cost calculation model with regional characteristics.The results show that the new method of mechanically checking by dividing expressway into three parts:main engineering,tunnel and interchange service area is feasible and reasonable.The fitness that establishing expressway engineering cost calculate model is high.Most of the measurement error is controlled within±10%,and the calculation accuracy is in good agreement with the actual engineering data,which can be used as an important reference for highway investment decision.
