PERFORMANCE AND ANALYSIS OF CONE PRESSUREMETER TESTS IN SANDS
This paper presents the results of tests performed in sand with a prototype cone pressuremeter. Values of shear modulus and friction angle of the sand are derived from the data using cavity expansion/contraction theory. These values are compared with those obtained from seismic cone penetration tests and self boring pressuremeter tests. The Paper aimes to stimulate the development of methods to evaluate and apply data obtained from tests in sands with this operationally convenient in situ test. The values of shear modulus obtained with the cone pressuremeter are compatible with those obtained from the other tests. The availability of a cone resistance profile provided by the cone pressuremeter, at the same location as the pressuremeter derived shear moduli, facilitates the production of a continuous depth profile of shear modulus based on a reliable site specific correlation. Available cavity expansion theory produces unrealistic values of peak friction and dilation angle from cone presssuremeter data. Available cavity contraction theory produces unrealistic values of friction and dilation angle from both cone pressuremeter and self boring pressuremeter data. Creep deformations contribute to the difficulties associated with the applications of cavity expansion and contraction theories. However, with appropriate test procedures the creep deformation can be identified. A standard test procedure is proposed to facilitate comparisons of data obtained from further tests in different sands. Such comparisons are needed to advance understanding of cone pressurementer test data.
