【摘要】 在面板混凝土施工配合比设计时,对混凝土的膨胀性进行补偿,加强混凝土施工过程控制,解决了堆石坝混凝土面板由于受几何尺寸和外部环境作用而产生横向收缩裂缝的问题.介绍了天台黄龙水库混凝土面板堆石坝的面板混凝土配合比设计和施工过程控制相结合的混凝土防裂技术的应用,在避免和减少施工后收缩裂缝方面收到很好的效果.更多还原

【Abstract】 In the mixproportion design of face slab concrete construction,the concrete crack control technology carries on the compensation to concrete expansibility,enhances the process control of concrete construction,and reaches the solution of transverse shrinkage crack of concrete slab of rock-fill dam produced by geometry size and external environment action.The application of slab concrete mit proportion design in rock-fill dam and concrete crack control technology in construction process are introduced,taking Huanglong Reservoir in Tiantai for the example,to avoid and seduce shrinkage crack after construction effectively.更多还原
