巨型桩大体积混凝土温度控制与监测

Temperature control and monitoring of the mass concrete of giant piles

大体积混凝土在桩基础工程中极为罕见,本文以深圳某金融中心巨型桩大体积混凝土施工为例,通过采取优化配合比及施工工艺等温控措施,并采用电阻型温度计对巨型桩桩身混凝土进行实时监测,对监测结果进行了分析总结,可为类似巨型桩大体积混凝土工程设计和施工提供有价值的参考。

Mass concrete is very rare in pile foundation engineerings.Taking the construction of massive concrete with giant piles in A Financial Center in Shenzhen as an example,the measures of optimizing mix ratio and isothermal control of construction technology as well as real-time monitoring of concrete with resistance thermometer for giant piles are applied.The monitoring results are analyzed and summarized,which can be used for the design of similar massive concrete with giant piles,and provide valuable reference for constructions.
