摘　　要：在水利工程建设施工中,填筑土料在碾压施工前均要做击实试验,以试验结果的最大干密度和最优含水率作为土料碾压质量控制的基本指标。有时在施工现场还要针对不同的土类进行抽样检验,保证其碾压控制指标的合理性。为能够快速处理击实试验结果数据,依据Excel提供的强大图表和内置函数功能,结合实际工程项目的土料击实试验,详细描述几种击实试验数据的处理方法及对比分析。In water conservancy projects,compaction test shall be carried out for filling soil before rolling construction,and the maximum dry density and optimum moisture content of the test results shall be taken as the basic indicators of soil rolling quality control.Sometimes at the construction site,sampling inspection shall be carried out for different soil types to ensure the rationality of its rolling control index.In order to process the compaction test data quickly,this paper describes the processing methods and comparative analysis of several compaction test data combined with the soil test data of actual engineering projects in detail based on the powerful charts and built-in functions provided by Excel.

关 键 词：击实试验 最大干密度 最优含水率 函数 多项式 系数
