摘要
在那比水电站的施工阶段，为保证大坝碾压混凝土的质量，以工艺试验为基础，严格控制原材料的品质和混凝土的配合比．并实施了有效的施工过程各工序的质量控制。试验结果表明，那比水电站大坝碾压混凝土各项性能指标均能满足设计要求。本文所介绍的大坝碾压混凝土质量控制的方法和要点，可为类似工程提供参考。
To guarantee the construction quality of Nab-i hydropowerdam roller compacted concrete, based on concrete process test, the quality of raw material and concrete mix ratio has been controlled stricted, and the efficient quality control measures on each construction procedure has been taken. From the test result, all the performance index of roller compacted concrete can meet the design requirements. The quality control methods of roller compacted concrete introduced in this paper can be used for reference in similar project.
