标准击实试验的一种数据处理方法研究

Study on the Method in Data Processing of Standard Compaction Test

传统的击实试验数据处理是作图法,难于定量对比分析,本文以最小二乘原理为理论基础,通过试验数据的整理分析,结合Excel软件,以残差最小为标准,找到了含水量与干密度的合理的拟合多项式的解析式,对击实试验数据进行了定量分析,该方法简单方便,可在土工试验数据处理中得到推广应用.

It is difficult to process the test data of standard compaction test accurately by using traditional method. The paper introduces a new way to process the data of standard compaction test on the basis of the theory of least square method. Compared with the least error, the paper presents the rational fitting polynomial by using the Excel. It is feasible to use the method to decide the result of the standard compaction test. The method is expected to put into use in processing other civil engineering test data.
