Development of vane testing equipment for foundation investigations

Abstract

The purpose of this thesis is to (1) study and present a summary of previous investigations, by others, of vane testing equipment, and (2) utilizing the results of previous Investigations, to design and manufacture a light-weight, compact, easily operated vane testing device for quickly obtaining the shear strength of soils in situ, and with this equipment .to make such field investigations as time permitted,, It should be stated here that the equipment mentioned is limited to use in relatively soft, fine-grained soils at depths of approximately thirty feet or less, and that it operates on a strain-controlled principle.
