The 'pressuremeter test' in geotechnical engineering measures:
Choose the correct answer
Penetration resistance (same as SPT)
In-situ lateral stress-strain characteristics, pressuremeter modulus, and limit pressure
Permeability of the aquifer
Shear wave velocity only
Correct Answer
B. In-situ lateral stress-strain characteristics, pressuremeter modulus, and limit pressure

Pressuremeter (Ménard, selfboring): cylindrical probe expanded radially in a borehole; measures pressure vs volumetric expansion. Gives: pressuremeter modulus EM (≈ soil stiffness in situ), creep pressure Pf, and limit pressure PL. PL used to estimate bearing capacity and lateral pile resistance. Advantage: tests soil in situ (minimal disturbance). Used in France, Canada.
