    Abstract

    The paper presents a simple and inexpensive device to measure the volume change of the pore-air of dry soil specimens in the drained triaxial tests under atmospheric conditions. The principle of the method was described by Bishop and Henkel (Bishop and Henkel 1962). The modified apparatus makes use of low-cost photoelectric sensors and computer control. The applicability of the method is demonstrated by a comparison with test data from conventional triaxial tests on water saturated specimens.
