数理统计法在土坝填筑碾压质量分析和评价中的应用

Application of mathematical statistics to analysis and evaluation of the earth dam filling and rolling quality

采用数理统计的方法对土坝填筑碾压干密度指标进行统计分析,借助碾压干密度的频率分布图、极差控制图以及局部返工处理前、后填土碾压干密度的变化情况的对比分析,全面地对坝体的碾压质量状况进行分析和评价,同时也对施工质量波动的主要影响因素进行了分析和判断。

Using the method of mathematical statistics for statistical analysis ofdry density of dam filling and rolling parameters, the density of the frequency distribution diagram, control diagram and poorcontrast of local rework processing, filling compacted dry density ＇of the compacteddry changes, analysis and evaluation comprehensively on the dam compactionquality, also the main influence on construction quality fluctuation are analyzed and judged.
