FRENCH SELF BORING PRESSUREMETERS (PAF 68 AND PAF 72). VOLUME I. EVALUATION

The pressuremeter is a soil exploration tool that can be used to determine the strength of soft soils in-place without resort to "undisturbed sampling" and lab tests. Strength determination is based on the theory of expansion of a cylinder in a circular borehole. The self boring concept advanced the practice of pressuremeter testing by eliminating need for a predrilled borehole. This two-volume report on Caltrans' evaluation of PAF 68 and PAF 72 is intended to provide practicing geotechnical engineers with a guide to pressuremeter testing, and an assessment of its potential value as a tool for soils exploration. Volume one is concerned with the concept and practice of self boring pressuremeter tests. A detailed description of the evaluation project is given and the potential of the self boring pressuremeter as a soils exploration tool is discussed.
