高寒地区高拱坝温控措施费用计算方法研究

Study on Calculation Method of Temperature Control Measures Cost of High Arch Dam in Cold Areas

高拱坝坝身混凝土浇筑过程中,若不采取严格的温控措施,极易产生温度裂缝。在工程可研、初设、甚至招标阶段拱坝温控措施费大多采用指标法估算。因其在工程投资中所占比重较大,合理计算其费用,对工程总投资控制而言意义重大。对高寒地区某双曲拱坝温控措施费用及其计算方法进行了研究。

It is easy to cause temperature leakage in the process of concrete placement of high arch dam if strict temperature controlmeasure is not taken. The cost of temperature control measure is usually evaluated with index method in feasibility study stage,preliminary design stage,and even bidding stage. Since the cost accounts large proportion in project investment,reasonablecalculation of the cost has great significance on controlling the total investment.
