户宋河电站——主坝填筑质量的统计特征

Filling Quality Analyses of the Earth Dam of Husonghe Power Station

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。

The mathematical statistics is applied to analyze the quality indexes of earth filling in the four zones, which are L-shaped drainage body, upstream dam, downstream dam and contact clay, of the earth dam of Husonghe power station. The filling quality of the dam is evaluated and the controlling indexes are discussed by means of statistic characteristic curves and indexes. The result shows that the filling earth of the dam has a good quality and it can meet the demands of design and the degree of compactness is well designed. It also shows that it would be better if the dry density and relative density had been designed a little big and the coefficient of permeability and optimum moisture content a little low.
