摘要
混凝土大坝结构中采用部分埋石混凝土浇筑,可削减混凝土强度增长期的水化热,减少浇筑混凝土温升引起的裂缝和混凝土骨料及胶凝材料的用量,降低工程造价。以某电源电站大坝为例,从埋石混凝土的设计方案、施工方法、质量控制措施几方面,对埋石混凝土在大坝中的应用进行了详细介绍。其实践经验可供类似工程参考。
Application of embedding stone concrete in the placement of some parts of the concrete dam structure can reduce the hydration heat during strength increasing period, the cracks induced by temperature rise of concrete pouring, the amount of concrete aggregate and cementing material, and the engineering cost. Taking a power source station as an example, the application of embedding stone concrete in dam construction was introduced from the aspects of design method, construction method and quality control measures of embedding stone. The practical experiences can be referenced by similar projects.
