LABORATORY STUDIES OF THE PRESSUREMETER TEST IN SAND

A series of tests is reported in which a self-boring pressuremeter has been expanded in a large sample of sand, approximately 1 M high by 1 M in diameter, contained in a triaxial test chamber. The pressuremeter has been either cast into the sample during sample preparation, or drilled into the prepared sample. The method of Hughes et al (1977) is used to obtain values of the angle of internal friction and the angle of dilation, and these values are compared with those obtained for the same sand in the simple shear apparatus. The theoretical limit pressure for the expansion of a cylindrical cavity in a finite body of sand is calculated, and the difference between the observed and calculated values of limit pressure is attributed to end effects. The effects of disturbance during drilling are examined by comparing a "drilled in" test with "cast in" tests. (Author/TRRL)
