夏特水电站引水隧洞冬季施工工效及成本分析

Analysis on Construction Efficiency and Cost of Headrace Tunnel of Xiate Hydropower Station in Winter

夏特水电站地处西北高寒地区,冬季混凝土施工效率下降明显,通过采用现场跟踪测定,结合全程视频录像技术,对引水隧洞冬季施工工效和成本进行对比分析,为类似严寒地区冬季隧洞衬砌混凝土造价预测和成本控制提供参考。

Xiate Hydropower Station is located in the alpine region of northwest China,and concrete construction efficiency drops significantly in winter.By adopting on-site tracking and measurement,combined with the whole process video recording technology,this paper carries out comparative analysis on the construction efficiency and cost of the headrace tunnel in winter,and provides reference for cost estimation of primary lining concrete in winter and cost control in similar severe cold regions.
