摘要
碾压混凝土坝由于选用低水泥用量、高粉煤灰掺量 ,在温度控制方面比常态混凝土坝有利 ,但所用材料大致相同 ,在结构上同属大体积混凝土 ,因此在施工过程中不可避免地产生坝面裂缝 ,就汾河二库大坝坝面裂缝产生的原因及处理方法作了介绍。
Rolled concrete dam is more advantageous than normal concrete in temperature control because low quality of cement and high mixture quality of coal ash are chosen.The material was almost same and all belonged to big volume concrete.Therefore,rifts in the surfaces of dams during construction are inevitable to appear.This paper introduced the causes of formation and handling measures for dam surface drifts in Fen River No.2 Reservoir.
