摘要
Abstract
Jin'anqiao RCC dam locates in mountain range in southwest China. The RCC construction is adversely impacted by the special climate in dam site of dry winter, hot and rainy summer, long-duration high temperature, small temperature difference in a year and large temperature difference between day and night. To ensure the construction quality of RCC, the inclined-layer placing technology was used, by which, the interval between layers can be shortened, a larger constructing surface can be covered with a smaller pouring intensity and large-scale flow process can be achieved. The core samplings show that the construction quality of inclined-layer placing is at the same level with that of horizontal layer placing in similar projects in China, and the temperature rise within the dam body is smaller.关键词
