Field Evaluation of French Self-Boring Pressuremeter Paf 76 in a Soft Deltaic Louisiana Clay

Source

The results of a field investigation carried out with the French self-boring pressuremeter PAF 76 in a soft deltaic clay deposit located in south Louisiana are presented. The in-situ test is performed using an electronic control and data acquisition system, monitored by an HP85 microcomputer. A brief description of the equipment used, the general in-situ test procedure, and the approach used for the interpretation of a standard expansion test are presented. General characteristics of the deposit as well as an outline of the testing program are summarized. The standard pressuremeter characteristics are then plotted versus depth and compared with results obtained using other testing methods at the same site (cone penetrometer, dilatometer, triaxial test). This comparison shows that the self-boring pressuremeter yields shear strength and elastic modulus values much higher than the other classical methods, which agrees with previously reported observations.
