采用数理统计方法，对户宋河电站主坝的Ｌ 型排水体、上游坝体、下游坝体、接触粘土四个分区的填筑质量的检测指标进行统计分析．根据各分区的统计特征曲线和统计特征指标，评价该主坝的填筑质量，并对其设计控制指标进行讨论．统计分析结果表明，户宋河电站主坝的填筑质量良好，能够满足设计要求．压实度设计指标比较合理，干密度和相对密度设计指标稍低，最优含水量和渗透系数设计指标稍高，对施工质量有一定影响
Mathematical statistics were used to analyze the testing indexes of the filling quality of L type drainage bodies, upstream dams, downstream dams and contact clays of the main dam of Songhuahe Hydropower Station. According to the statistical characteristic curve and statistical characteristic index of each subregion, the quality of filling of the main dam is evaluated and its design control index is discussed. The statistical analysis shows that the main dam of Hunsonghe Hydropower Station has a good filling quality and can meet the design requirements. The design indexes of compaction degree are reasonable, the design indexes of dry density and relative density are slightly lower, the design indexes of optimal water content and permeability coefficient are slightly higher, which will affect the construction quality to a certain extent
