EVALUATION OF DIFFERENT SOIL SHEAR STRENGTH TESTING PROCEDURES TAKING INHERENT SOIL VARIABILITY INTO ACCOUNT
Historically, the Workload design method has served as the foundation for geotechnical designs. This approach relies on global safety factors which does not guarantee a sufficient margin of safety against every uncertainty involved in design. Limit states design accounts for probable failure by using partial safety factors for characteristic values to obtain a design value. Characteristic values are determined based on probability theory and statistical distributions. To obtain reliable probability density functions a large dataset of measurements is required to increase confidence in parameter values and statistical reliability. It is unfeasible to establish the 5th percentile of a soil parameter for most shear strength tests due to time and expense. This research evaluates three testing methods to obtain reliable probability density functions for more reliable data analysis and a less conservative characteristic value.
