The pore water pressure controlling device, PCD, which is capable of controlling a hydraulic gradient in a triaxial specimen during primary consolidation, was developed. It is considered that by installing the PCD between the specimen and the burette located along the drainage line, the condition of stress and strain in the specimen can be maintained approximately uniform during consolidation. In this paper, the principle and working mechanism of the developed PCD are first introduced. Then, based on a series of consolidated undrained triaxial compression tests on Kaolin clay, performed with the PCD under a variety of consolidation time, the relationship between the shear strength properties and the degree of consolidation is quantitatively evaluated.
