摘　　要：针对官地水电站大坝工程建设施工工期紧、建设施工技术难度高、强度大、施工区昼夜温差大等诸多不利于碾压混凝土施工的难题,通过施工场地和机械的布置、短间歇厚升层快速施工、配合比设计、温控防裂、GPS监控系统使用等关键技术的优化,确保了碾压混凝土施工如期完成。It is great difficult for roller-compact concrete construction in the Guandi Hydropower Station under the conditions of limited time,technical complexity,high construction strength,big temperature difference between day and night,etc.However,such a complex project can be accomplished by taking advantage of layout of construction site and machinery,combined with such improved techniques as short-interval thick lift fast construction,design of mix proportion,temperature control and crack prevention,and GPS supervisory system.
