ABSTRACT

A form of pressuremeter can be used in all ground conditions, and ground properties are obtained either directly, theoretically or empirically from a pressuremeter test. The results of pressuremeter tests are used to produce design properties directly, to determine intrinsic properties by applying constitutive models to interpret the data, to validate more complex constitutive models used in numerical methods and as a means of control in ground-improvement schemes. Bearing resistance and settlements of shallow and deep foundations can be predicted with a degree of confidence using the Ménard pressuremeter. Ground properties including total horizontal stress, stiffness and total and effective strength parameters from pressuremeter tests are used to create site-specific empirical correlations, validate constitutive models, and produce profiles of mechanical properties to be used in design. The pressuremeter is used in conjunction with other tests to produce comprehensive ground models.
