Determination of Critical State Parameters in Sandy Soils-Simple Procedure

摘要

The critical state is arguably the most robust crite- rion for strength design, including post liquefaction strength. The conventional triaxial test is used for the determination of critical state parameters; however, it is time-consuming and the required set of tests is relatively expensive for common geotechnical tasks. A simplified test procedure is developed to determine the critical state line in sandy soils. The procedure is reliable, economical, and fast.
