Pressuremeter test

A pressuremeter is a meter constructed to measure the “at-rest horizontal earth pressure”. The pressuremeter has two major components. The first component is a read-out unit that remains above ground. The second component of the pressure meter is a probe that is inserted into the borehole (ground) to read the pressure.

In principle, the pressuremeter test is performed by applying pressure to the sidewalls of a borehole and observing the corresponding deformation.

PRINCIPLE OF THE MENARD PRESSUREMETER TEST. He also proposed to di led to new trends in the cost effecti. He compiled a large data base of load tests and companion pressuremeter tests to refine his empirical design formulas and persuade other engineers to use the PMT.

To show his confidence and encourage acceptance of the test, Menard guaranteed foundation designs based on the PMT with $1000of professional . The interpretation of the pressuremeter test must take account of the disturbance caused by the method used to place the probe in the ground. The least disruptive of the methods is self boring where disturbance is often small enough to lie within the elastic range of the material and is therefore recoverable. From the test readings (volume variation based on controlled pressure), a stress-strain curve can be obtaine in the case of plane .

In Situ SI offer a full range of pressuremeter testing services including cone pressuremeter, self boring pressuremeter and high pressure dilatometer.

Withdrawn Rationale: This test method covers pressuremeter testing of soils. To obtain viable test , disturbance to the borehole wall must be minimized. This chapter focusses on another insitu test, the pressuremeter. The Menard type pressuremeter and the self boring pressuremeter are described including the test procedures and stress relaxation at the commencement of the test.
