A MICRO-COMPUTER SYSTEM FOR THE VERIFICATION OF SOILS CONSTITUTIVE MODELS. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM HELD IN NIAGARA FALLS, CANADA, 8-11 MAY 1989

A program run on an hp 310 for verifying soils models is presented in this paper. It is composed of a data processing package, a databank of laboratory tests carried out on different materials, and a library of constitutive models. The databank contains conventional triaxial, triaxial and torsional tests carried out on various materials. It also contains standard paths which are used in test validation. The library contains the following models: cam clay (1968); lade (1977); nova (1982) and vermeer (1978). These enable the user to compare results obtained by a new model with those obtained with known models. The data processing code is composed of 3 programs: data construction; models integration; and results processing. The results processing program produces results in graphic form. The system offers two types of verification test: (a) tests against experimental data; and (b) tests of model theory, such as model sensitivity to error sources or to parameter perturbation, or the models predictions of particular paths. The tests using experimental data are illustrated using nova's model predictions. The system is also used to compare predictions forecast by nova's model with those forecast by lade's model.
