Abstract
The cyclic triaxial strength test is commonly applied as a laboratory test for evaluating the liquefaction resistance ratio. However, the test procedure was not standardized in South Korea until recently; thus, the test results could significantly differ depending on the performer and apparatus, even when identical soil is used. In this study, the American and Japanese standards for the cyclic triaxial strength test were analyzed and the Korean standard was developed considering domestic circumstances. To verify the effectiveness of the standardization of liquefaction laboratory tests, several cases of cyclic triaxial strength tests were conducted and analyzed (1) following the Korean standard and (2) without following any specific instructions for the test procedure. Under (1), the deviation of the liquefaction resistance ratio dramatically decreased.
