ABSTRACT:
The dilatometer test (DMT) has been shown very useful in providing several geotechnical parameters, in different types of soils. The test is regularly carried out every 20 cm, i.e., it is a discontinuous test. Therefore, its capability of detecting variations in the geotechnical profile is conditioned by the test interval. The Medusa DMT, however, is able to obtain continuous measurements of the A reading, thus providing a much better picture of the soil stratigraphy. Medusa DMT tests have been carried out at Sarapuí II very soft clay deposit around Guanabara Bay, in Rio de Janeiro, and a detailed soil profile was obtained. A comparison was made with piezocone tests. The stratigraphy of the deposit obtained by both tests was almost the same.
