公路工程造价是公路建设项目的重要组成部分之一,高寒地区地理气候特殊性对公路工程造价有着重要影响。本文以西藏境内国道219线新藏公路为例,论述了高寒地区公路建设的气候特征和施工条件的特殊性,针对该地区气候差、运输困难、施工期短、施工效率低等特点,研究了人工费、材料费、机械使用费、其他工程费等对公路工程造价的影响,研究结果对合理控制国道219线新藏公路的工程造价有着重要作用,并对类似地区的公路工程建设有重要借鉴意义。
The cost of highway construction is one of the important components of highway construction project. The special geographical and climatic characteristics of the alpine region have an important impact on the highway construction cost. Taking the Xinjiang-Tibet Highway on State Road 219 in Tibet as an example, this paper discusses the climatic characteristics and construction conditions of highway construction in the alpine region. In view of the characteristics of poor climate, transportation difficulties, short construction period and low construction efficiency in this area, The results of the study have an important role in the reasonable control of the construction cost of the National Highway 219, the Xinzang Highway, and have an important reference to the construction of highway projects in similar areas significance.
