摘　　要：为探明不同施工工艺下跨汉江大桥大体积混凝土水化热控制效果,优化施工工艺,对湖北省某跨汉江大桥主桥不同主墩承台采用不同浇筑方式进行研究。通过温度场实测,得出大体积混凝土承台采用分层浇筑施工工艺较一次性浇筑水化热控制效果更佳。In order to verify the hydration heat control effect of mass concrete of a Hanjiang bridge under different construction technologies and optimize the construction technology,different pouring methods were studied for different main pier caps of a Hanjiang bridge in Hubei Province.Through the actual measurement of temperature field,it is concluded that the layered pouring construction technology is better than one-time pouring to control the hydration heat of mass concrete cushion cap.

关 键 词：大体积混凝土 水化热控制 施工工艺优化
