> A recent intervention on a site in southern Brazil shows the consistency of the values of tensile forces obtained from the vibration analysis tests with the values deduced from the calculation of earth pressure on the retaining wall (photo attached).

The interpretation of the non-destructive testing is improved when it relies on static tests performed in conjunction with dynamic tests. The tests on the anchoring rods are adapted to semi-infinite massifs.
