摘　　要：为了简化击实试验的过程、缩短试验周期、提高工作效率,选择河北省内高碑店、邢台、石家庄等地水利水电工程项目中123组土的击实试验数据进行统计分析,得到了土的液限与最优含水率、最优含水率与最大干密度的线性回归方程,并应用实例证明线性回归方程的适用性。In order to simplify the process of compaction test, shorten the test cycle, improve the work efficiency, it chooses 123 soil compaction test data of hydropower engineering projects of Gaobeidian, Xingtai, Shijiazhuang and other places in Hebei province for statistical analysis, and gets the soil liquid limit and the optimum moisture content, the linear regression equation of the optimum moisture content and maximum dry density. Then the applicability of the linear regression equation is proved by an example.

关 键 词：击实试验 土样制备 液限 最优含水率 最大干密度 线性回归分析
