ABSTRACT: Improvements to the measurement of undrained shear strength have occurred recently with the adoption of the Ball Penetrometer Test and the electric vane shear device. The use of a computer controlled torque recording unit has greatly enhanced the accuracy of the field vane test. Undrained shear strength and soil stiffness are profiled at one soft soil site in Surrey, BC. Data is presented from both test methods for peak and remoulded strengths. These results are also compared to the standard CPTU and Dilatometer. Small strain soil stiffness data based on shear wave velocity is also presented using both in-situ and surface methods. The combination of the Electric Vane Shear testing and flow penetrometer testing provides a site investigation approach applicable to slope stability hazards.
