Characterization of Materials Behaviour by the Pressuremeter Test

At least five different methods are available to interpret the results of field pressuremeter tests for saturated clays, each of which has been reported to yield different values of soil parameters when applied to the same pressuremeter test. In the present investigation, a laboratory pressuremeter model was developed, and simulated pressuremeter tests were run on a sedimented Kaolinite consolidated to different values of the maximum vertical pressure, gs v , and with overconsolidation ratios OCR ranging from 1 to 8.

The pressuremeter test is an in situ, stress-strain test performed on the wall of a test cavity using a circular cylindrical probe that is expanded radially. To obtain viable test results, disturbance of the test cavity must be minimized with minimal clearance between the diameter of the probe and the test cavity. Alternatively, when preboring does not provide an acceptable test cavity, the probe may be directly inserted into the ground to form the test cavity. Knowledge of the type of soil to be tested is necessary for assessment of 1 the method of preparing the test cavity, 2 the interpretation of the test data, and 3 the acceptability of the test results. This test method is limited to the type of pressuremeter that is inserted into predrilled boreholes or, under certain circumstances, is inserted by driving or pushing.

Figure A-1 shows a schematic of the pressuremeter test setup. 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.
