Applying vacuum in one dimensional and isotropic test carried out in remolded material

摘要

The technique of soft soils improvement with vacuum consolidation is more and more used, inrndifferent places around the world, because it offers a series of advantages compared with other techniques of softrnsoils improvement, depending of the kind of project.The laboratory tests are important sources of information forrnprojects of soft soils improvement. In this work are presented the procedures and the results of one-dimensionalrncompression test (consolidation press) and isotropic compression test (the triaxial cell), applying vacuum andrnusing remolded material. For made this, was necessary the development of procedure for the applying vacuumrnin the tests. Difficulties happened during this development, this situation forced to test different techniques untilrnto obtain a satisfactory operation.With the development of the procedures was done a series of tests to know thernresults that these tests provide.With the results obtained were done analyses for its interpretation. It was provedrnexperimentally that the vacuum works as a loading for the consolidation of soft soils.
