摘　　要：三轴试验是测定土的应力-应变关系和强度的一种常用的室内试验方法,其试验成果对地质工程设计、岩土稳定分析等领域具有重要的参考价值。三轴试验数据处理是试验结果分析的关键环节。概述了三轴试验方法和确定土的抗剪强度基本原理,介绍了抗剪强度的不同求解方法,并做了相应的优劣分析,分析表明基于最小二乘法的Excel规划求解结合归一化法能为工程的设计与施工提供更为科学、可靠的依据。Triaxial test is a common laboratory test method to determine the stress-strain relationship and strength of soil,and its test results have important reference value for geological engineering design,geotechnical stability analysis and other fields.Triaxial test data processing is the key link of test result analysis.This paper first outlines the triaxial test method and the basic principle of determining the shear strength of soil,and then introduces different methods of solving the shear strength and makes the corresponding advantages and disadvantages analysis.The analysis shows that the least square method combined with Excel programming and normalization method can provide a more scientific and reliable basis for the design and construction of engineering.
