摘要
后溪河水电站中咀坡大坝为混凝土面板堆石坝,在填筑前进行了大型碾压试验。针对不同填筑区筑坝材料的铺料厚度、铺料方式、碾压遍数、碾压速度、加水量等施工参数进行碾压试验,在获得大量真实有效试验数据的基础上,运用数理统计和EXCEL图表分析法对试验数据进行了综合分析,据此确定合理的施工参数。通过对碾压试验资料的分析提出了合理的填筑施工参数及质量控制指标,并且该工程的碾压试验结果也可为同类工程建设参考。
The Tsui slope of Houxi River Hydropower is a concrete faced rockfill dam, Being filled in large - scale compaction tests have been carried out. To point against the dam compaction of spreading thickness of the dam materials, the way of the material paved, rolled several times, rolling speed, the amount of the adding water and other construction parameters in different reclamation area, based on a large number of real and effective the test data, we used the method of mathematical statistics and EX- CEL chart analysis to analysis test data and to determ the reasonable construction parameters. Through the test data analysis the anthor puts forward the reasonable filling construction parameters and quality control index, and the conpaction test results can be used for reference of similar projects.
