| 摘 要： | 重力式锚碇是典型的大体积混凝土结构,施工过程中的水化热应予以严格控制,避免产生温度裂缝.以郭家沱大桥锚碇为例,在施工前进行水化热分析,制定相应的大体积混凝土温控措施.经现场监测,各项指标均满足标准限值,未出现混凝土温度裂缝,证明温控措施有效,确保了锚碇质量.

| Abstract: | Gravity anchorage is a typical massive concrete structure.The hydration heat during construction should be strictly controlled to avoid temperature cracks.Taking guojiatuo bridge anchorage as an example, hydration heat analysis is carried out before construction, so as to formulate corresponding temperature control measures for massive concrete.Through field monitoring, all indexes meet the standard limits, and no concrete temperature cracks are found, which ensures the quality of concrete. |

| Keywords: | anchorage massive concrete hydration heat temperature control |
