三轴试验是一种重要的土工试验方法,同样不可避免地存在各种误差,随着电子技术的发展,高精密电子量测元件、数据自动化采集系统的应用,使三轴试验的精度得到较大提高,试验数据也变得极为丰富,如何从如此繁杂的数据中提炼出正确有效的数据则是有待解决的问题。以三轴试验测得土体应力应变关系曲线为例,基于土的变形特性,论述了如何扣除试验的系统误差。
Triaxial test is an important method of geotechnical test. It is also inevitable that there are various errors. With the development of electronic technology, the application of high precision electronic measuring devices and automatic data acquisition system makes triaxial test more accurate Big increase, the experimental data has also become extremely rich, how to extract the correct and effective data from such complicated data is the problem to be solved. Taking the stress-strain curve of soil measured by triaxial test as an example, the systematic error of the test is deduced based on the deformation characteristics of soil.
