SELF-PROPELLED DRILLING PRESSIOMETER

LE PRESSIOMETRE AUTOFOREUR

Details are given of the modifications to the pressiometer used for in-situ soil tests with a view to extending the possibilities of the device for soil investigations, foundation design, and the study of the basic mechanical characteristics of loose fine soil. The patented modifications (self-drilling system) permit the in-situ testing of undisturbed soil with great accuracy. Thanks to the theory of cylindrical expansion, test results can now be interpreted with great precision. Results are presented of measurements made on a number of sites: earth pressure at rest; shear stresses and intergranular stresses. Mention is made of different aspects of pressiometer stresses in relation to the behaviour of piles subjected to horizontal stresses: undrained rapid loading, or drained slow loading, cyclic loading, influence of disturbed zone, and creep. /TRRL/
