Abstrakty
The sections of dam around Grenoble are the subject of a geotechnical campaign based on the use of a geophysical method, the electrical panel. Practice shows that the detection of the seepage, heterogeneities, the geometry, the nature of the layers obtained by the electric analysis is not always in conformity with an objective reality, but that the method of inversion leads to an uncertainty which can be important. Research allows us to reduce the errors of this method by taking into account of the geometries when they are known. Pressuremeter tests with cycle were carried out and interpreted in inverse analysis to determine the mechanical characteristics of elasticity and resistance with the methods developed with the L3S-R. Lefranc tests, for the determination of the permeability of materials of the dam, were also carried out. The results are gathered and compared with measurements in laboratory for a better analysis of the risk of instability.
