摘要
结合锦屏一级水电站拱坝混凝土施工期的全级配、湿筛试件所测试的各项试验结果,分析了坝体A区、B区、C区混凝土的抗裂性能。指出:因不同评价指标的物理意义不同,各个指标之间评价结果亦不同。结论认为:采用综合指标开展评价,能较好地体现混凝土的实际抗裂性能,对于施工期防裂分析具指导意义。
In accordance with all the testing results from the concrete specimens of the full-graded and wet-screened tests made during the construction of the arch dam for Jinping I Hydropower Station, the concrete cracking-resistances of the zone A （C18040）, zone B（Cts035）, zone C（C18030） therein are analyzed, and then it is pointed out that as the physical meanings are different for various evaluation indexes, the evaluation results among all the evaluation indexes are also different. Therefore, it is concluded that the application of the comprehensive index to the evaluation can give out the actual cracking-resistance of the con- crete preferably; which has a guiding significance for the analysis made on the cracking-resistance during the construction.
