Abstract : This report consists of (1) a general discussion of the problems involved in pore pressure measurements during transient loadings, (2) a description of the conventional pore pressure measuring systems and their inadequacies, (3) descriptions of the design and preliminary testing of a new system for pore pressure measurement using a PT 25 Dynisco pressure transducer, (4) a detailed presentation of data obtained in tests in which the new pore pressure measuring system was employed, and (4) a discussion of results of the testing and the implications of these results. The feasibility of employing the new pore pressure measuring system in rapid testing has been demonstrated by the following tests: (a) onedimensional tests on fat clay and silty loam, (b) triaxial tests on a saturated clayey-silt, and (c) triaxial tests on a fat clay.
