坝顶临时道路成本最优的影响因素研究

Study on the Influencing Factors of Optimal Cost of Temporary Road at the Dam Top

临时道路成本是影响工程项目成本的一项重要因素,控制并减少临时道路成本是进行工程成本管控的有效方法。本文将临时道路成本分为内部因素和外部因素,采用层次分析法中1~9标度法对指标之间的重要性进行量化。通过研究发现,在影响成本的因素中,施工直接费用权重值为0.4080,对坝顶临时道路的成本影响作用尤为突出;施工方案和征地费用权重值分别为0.2170和0.1820,二者对坝顶临时道路成本有较大影响,施工企业在坝顶临时道路的成本管理中应该对二者给予足够的关注;地形地貌、设计变更和工期,权重值分别为0.0872、0.0700和0.0359,虽然三者对坝顶临时道路成本的影响相对较弱,但对于管理能力较强的施工企业,三者也应该成为实现坝顶临时道路成本最优的有力抓手。

Temporary road cost is an important factor affecting the cost of a project. Controlling and reducing the cost of temporary roads are an effective method for engineering cost management and control. This article divides the cost of temporary roads into internal factors and external factors, and uses the 1 - 9 scale method in the analytic hierarchy process to quantify the importance between indicators. Through research, it is found that among the factors that affect costs, the direct construction cost weight value is 0.4080, which has a particularly significant impact on the cost of temporary roads at the dam roof;the construction scheme and land acquisition cost weights are 0.2170 and 0.1820, respectively, which affect the temporary dam roof. Road costs have a large impact, and construction companies should pay sufficient attention to the two in the cost man-agement of temporary roads at the dam top;topographic features, design changes, and construction periods have weights of 0.0872, 0.0700, and 0.0359, although the three have a relatively weak impact on the cost of temporary roads, for construction companies with strong management ca-pabilities, the three should also be a powerful hand to achieve the optimal cost of temporary roads at the dam roof.
