PRESSUREMETER TESTING OF SOILS

The author reviews the development of the pressuremeter soil test apparatus from the introduction of the menard instrument in 1954. The test method is based on inserting an inflatable instrument in a borehole and, from pressures developed, elastic modulus and shear strength can be calculated. A development in apparatus design in 1960 was the introduction of the self boring design able to form its own borehole. The self-boring instruments provide pressure/strain graphs giving strength, stiffness, in-situ stress and pore-water pressure. A further development comprised two instruments - a load cell pressuremeter to give in-situ stress and pore water pressure, and also an expansion pressuremeter providing a shear stress/strain graph with a measurement of in-situ stress in three directions, and also the effective pressure due to the soil alone. The article concludes by evaluating the advantages and disadvantage of such equipment. (TRRL)
