地形因素对高速公路建设时产生的能源消耗起到决定性的影响。针对工程量、场地条件等与地形直接相关的特点,引入路基单位公里计价土石方量、桥隧比以及重丘比例等3个基础指标,将3个基础指标作为影响因子进行系统聚类,按照聚类结果对高速公路建设期的单位能耗进行划分并证明了划分后的单位能耗服从正态分布。利用层次分析法,计算得到3个基础指标的权重,给出了不同地形下的定额地形分类指标的计算方法及待评估道路的地形分类指标计算方法,提出了高速公路建设期能耗的快速分类方法,为下一步高速公路建设期能耗统计定额的计算及完善打下了基础。
Topographic factors have a decisive impact on the energy consumption of freeway construction. According to the characteristics of engineering quantity and site conditions, which are directly related to the terrain, three basic indicators such as the earth-rock mass per unit km, the ratio of bridge to tunnel and the ratio of heavy hill are introduced. The three basic indicators are clustered systematically as the influencing factors, The results of the classify the unit energy consumption of expressway during the construction phase and prove that the unit energy consumption of the divided unit follows a normal distribution. Using AHP, the weights of three basic indexes are calculated, and the calculation methods of the index of topographic classification under different terrain and the calculation method of terrain classification index of the road to be evaluated are given. The rapid classification of energy consumption during the construction of expressway is proposed Method, laid the foundation for the calculation and improvement of statistical quotas for energy consumption in the next highway construction period.
