Menard presuremeter test is an in situ stress controlled loading test performed on the wall of the borehole using cylindrical probe which can expand radially. From the readings, stress strain curve can be obtained which yields : a. the presuremeter modulus b. the creep presure (yields presure) c. the limit presure (failure presure) Figure A.6.1 shows schematiic diagram of Menard presuremeter test and typical test curves 1.2 Equipment (1) The Monitoring Unit Equiped with device to preciesly regulate the presure applied to the probe and read is volume change with presure increment and time. A gas cylinder provides the pressure source. It includes a 800 cm3 volumeter with sight of tube, a main pressure a regulator , a differential presure regulator, presure gauge 0-2.5 and 0-6 Mpa for the measuring and guard cell (0.06 and 10 Mpa as option for soft soil and weak rock test) and the necesary valves and coupling. (2) The palstic tubing Thi...
