利用回归和数值分析求取击实试验极值的方法探讨

Obtain the Extremum of the Compaction Test by the Regress Analysis Method and the Numerical Analysis Method

利用回归分析法和数值分析法对击实试验数值进行分析,可以较准确地求出最大干密度和最佳含水量。同时利用电子表格绘图并处理试验数据,特别是用数值分析法与绘图相组合,可以提供较为准确的试验结果。对这两种方法的应用进行分析探讨。

Using the regress analysis method and the numerical analysis method to obtain the extremum of the compaction test, we may accurately extract the biggest dry density and the optimum moisture content. Using the electronic forms to draw pictures and process the test data, especially combining the value analytic method with the cartography, it may provide more accurate test result. It is worth being used widely.
