Abstract

In the discipline of geotechnical Engineering the majority of finite element program users is familiar with the hyperbolic soil model. The input parameters are commonly obtained from a series of triaxial tests. For cohesionless soils however, today's sampling techniques fail to provide undisturbed soil specimen. Furthermore, routine triaxial tests can not be carried out on soils with grains exceeding 10 - 15 mm in size.

Initial developments towards a link between high quality pressuremeter tests and the hyperbolic finite parameters element input are presented. Theoretical and empirical approaches are used to determine the entire set of and from pressuremeter tests. Triaxial pressuremeter tests are performed on the same soil. The proposed method is evaluated using a finite element program for axisymetric solids modelling pressuremeter tests as well as a model foundation. The computer solutions are compared to the response of a physical model foundation under load application.
