摘　　要：土的物理力学指标是地基基础设计和施工的重要依据,土力学试验数据量大,计算工作繁琐。以界限含水率试验为例,阐述了试验原理和试验方法,得到了液塑限的解析法,使用MATLAB编制和调试程序,实现了试验数据自动计算、绘图和分析等过程。采用该程序处理了某实际工程试验数据,结果表明,该方法计算速度快,精度高,得到的双对数图形规范而美观,效果良好,为土力学实验数据分析提供了参考。Since soil mechanics experiment has large amounts of data, the work of processing data is very complicated. Taking critical moisture content experiment for example, experiment principle and means are explained, the analytical method of liquid and plastic-limit is deduced, and the process about how to calculate, plot and analyze data automatically using MATLAB is described. The data of a project are investigated using the proposed method. The result shows that the method is easy to process; from the data the normative and excellent double logarithmic graph can be obtained.
