Triaxial tests are often used to determine the behavior and strength characteristics of soils for geotechnical engineering analysis and design. Triaxial testing involves many sources of error that could significantly affect shear strength parameters if not corrected. These errors and the available correction methods are thoroughly reviewed in this study in a series of monotonic triaxial compression tests on loose Ottawa sand specimens. The significance of each correction on the triaxial test results and the achieved adjustments of the shear strength parameters and void ratio are discussed and evaluated. It is found that negligence in making corrections accounting for these errors could result in an overestimation of as much as 44% and 14.7° in the measurement of undrained and drained shear strength parameters, respectively.
