摘　　要：通过CBR试验对击实试验中数据进行处理,采用Excel中二项式拟合、三项式拟合工地试验软件得出最佳含水率和最大干密度,并进行对比验证,以期得出相对适宜的确定方法,通过试验发现二项式拟合所得结果最理想。Through CBR test,the best moisture content and the maximum dry density obtained from the data processing in the compaction test using binomial fitting and trinomial fitting in Excel and site test software were compared and verified,in order to obtain a relatively suitable determination method,it is found that the best result of binomial fitting is obtained through the experiment.

关 键 词：土工击实试验 曲线确定 最佳含水率 最大干密度 CBR值
