PRESSUREMETER TEST
The pressuremeter test is an in-situ testing method which is commonly used to achieve a quick and easy measure of the in-situ stress-strain relationship of the soil which provides parameters such as the elastic modulus.
DESCRIPTION AND PROCEDURE
The pressuremeter test is an in-situ testing method used to achieve a quick measure of the in-situ stress-strain relationship of the soil. In principle, the pressuremeter test is performed by applying pressure to the sidewalls of a borehole and observing the corresponding deformation.
The pressuremeter consists of two parts, the read-out unit which rests on the ground surface, and the probe that is inserted into the borehole (ground). The original Ménard-type pressuremeter was designed to be lowered into a performed hole and to apply uniform pressure to the borehole walls by means of inflatable flexible membrane. As the pressure increases, the borehole walls deform. The pressure is held constant for a given period and the increase in volume required for maintaining the constant pressure is recorded. A load-deformation diagram and soil characteristics can be deduced by measurement of the applied pressure and change in the volume of the expanding membrane.
The major difference between categories of pressuremeter lies in the method f installation of the instrument into the ground. Three main types of pressuremeters are:
The borehole pressuremeter: The instrument is inserted into a performed hole.
