THEORETICAL AND EXPERIMENTAL ANALYSIS OF THE COMPRESSIBILITY OF PORE FLUID IN A NEARLY SATURATED CLAYEY SOIL

THIS PAPER WAS PRESENTED AT THE INTERNATIONAL SYMPOSIUM ON SOFT CLAY, BANGKOK, THAILAND, 5-6 JULY 1977. THEME: COMPRESSIBILITY AND SETTLEMENT OF SOFT CLAY. QUASI TWO-PHASE SOIL MODELS (SATURATED WITH A COMPRESSIBLE LIQUID) COMPRISE A COMPRESSIBILITY COEFFICIENT A INDEX W FOR THE PORE FLUID. IN THE FIRST PART OF THIS PAPER A THEORETICAL FORMULA IS DERIVED FOR A INDEX W, WHICH IS VERIFIED EXPERIMENTALLY. A BRIEF DESCRIPTION IS GIVEN OF THE OEDOMETER WITH PORE WATER PRESSURE GAUGES, THAT WAS USED IN THE EXPERIMENTAL STUDY TOGETHER WITH THE PRINCIPLE OF THE TESTS AND RESULTS OF REPRESENTATIVE TESTS. TAKING INTO ACCOUNT THE RANGE OF ACCURACY OF THE THEORETICAL AND EXPERIMENTAL VALUES, THEORY AND EXPERIMENTS SHOW A FAIRLY GOOD AGREEMENT.
