摘要
金安桥水电站大坝工程规模大、工期紧、技术复杂、施工强度高。针对其玄武岩骨料碾压混凝土可碾性差、坝体布置复杂以及立体气候条件明显等诸多不利于碾压混凝土施工的难题,通过配合比设计、入仓方案、仓面分区、层间结合、温控防裂等关键技术的优化和技术创新,保证了碾压混凝土快速施工和度汛等重大节点工期目标的按期实现。
The poor roller characteristic of RCC with basalt aggregate, complex dam layout and significant air temperature change with elevation have adverse impacts on the construction of Jin＇anqiao RCC dam. Through optimizing mix proportion design, placing solutions, placement blocking, the integrating of RCC lifts and the temperature control for crack control, the rapid construction for RCC is achieved and the major construction objectives are completed on time.
