The paper is concerned with the use of a self-boring pressuremeter to obtain in situ measurements of the properties of sands. A brief description of the instrument and of its method of operation is given. A review of the interpretation of pressuremeter tests in sand is presented and a new interpretation is described in which allowance is made for the volume change that occurs in sand when it is sheared. It is assumed that the stress-dilatancy theory is valid, and that sand fails with a constant ratio of principal stresses. The analysis allows a value for the angle of internal friction and a value for the angle of dilatation to be determined. Experimental results of tests in sand at the wash and in the hydraulic fill at the Kernick Dam are presented; the resulting values of the angle of internal friction are compared with those deduced from cone penetration tests and triaxial tests. Values of shear modulus and in situ horizontal stress are also measured and reported. /Author/TRRL/
