Simple numerical methods that allow to obtain stress and strain paths in sand during self-boring pressuremeter tests are presented in this paper. The material is considered to undergo deformation in drained and plane-strain conditions. The flow rules of Rowe, Cambridge-type (Cam clay and Nova) model, and the sawtooth model are used in the analysis. Elastic strains are also considered in relation with the flow rule of Rowe. The proposed approach has been evaluated using a reference pressuremeter test performed on Ticino sand in a calibration chamber. The results indicate that the stress–strain–volume change responses of the sand predicted by the various models are quite similar, with and without consideration of the elastic strain components.

And Behavior

It is not simple to determine in-situ horizontal stresses even though vertical stresses could be determined directly. Pressuremeter is not given high importance even though it is useful in illustrating various geotechnical parameters effectively. It is important to characterize geomaterials which in turn helps us to understand the properties and behavior of the materials. Symbolic Regression model has been prepared to relate pressuremeter test results with geotechnical engineering properties. Understandingthese properties help geotechnical engineers in design and analyses of foundations, earth pressures, etc.

The Given

The results of short-term pressuremeter tests from three different sea ice environments are presented. These results are used to derive mechanical properties of the ice, to compare the ice types, and to evaluate the Texam pressuremeter as an instrument for the field assessment of ice sheets and ice packs. The results are also compared with those existing in the literature. It was found that the strength of the sea ice was affected most significantly by temperature, but also by salinity and to a lesser extent by confining pressure and ice structure. The Texam pressuremeter operated well in the given field environment and will prove to be a valuable piece of equipment for determining the characteristics of these important ice formations. Key words : pressuremeter, sea ice, short-term tests, strength, salinity, confining pressure, temperature.

Interpretation Method

Traditionally pressuremeter tests results are interpreted using only the loading pressure–expansion data. An interpretation method has been developed that makes use of both the loading and unloading portions of a pressuremeter test and incorporates nonlinear, undrained soil behaviour. This method has been modified to handle large trains. The proposed interpretation accepts that some level of soil disturbance exists during the early stages of a pressuremeter test, and hence more emphasis is placed on the unloading portion of the test. A methodology is described to allow this interpretation procedure to be applied to self-bored, prebored, and full-displacement undrained pressuremeter tests. The proposed method is evaluated using self-boring and full-displacement pressuremeter test results from various published field projects. The interpretation is accomplished using commercially available microcomputer software that can perform the curve-matching process for both loading and unloading portions of the test. Key words : pressuremeter, loading data, unloading data.
