The Tsui slope of Houxi River Hydropower is a concrete faced rockfill dam, Being filled inlarge-scale compaction tests have been carried out.To point against the dam compaction of spreadingthickness of the dam materials, the way of the material paved, rolled several times, rolling speed, theamount of the adding water and other construction parameters in different reclamation area, based on alarge 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 detenn the reasonable construction parameters.Throughthe test data analysis the anthor puts forward the reasonable filling construction parameters and qualitycontrol index, and the conpaction test results can be used for reference of similar projects.
