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。
Soil physical and mechanical indicators of foundation design and construction is an important basis for soil mechanics test data, calculation work cumbersome. In this paper, the experiment of limit moisture content is taken as an example, the test principle and test method are expounded, the analytical method of liquid-plastic limit is obtained, the process of automatic calculation, drawing and analysis of test data is realized by using MATLAB programming and debugging program. The experimental data of an actual project was processed by this program. The results show that the proposed method is fast and accurate, and the double logarithmic graph obtained is of good quality and good effect, which provides a reference for the experimental data analysis of soil mechanics.
