SUMMARY:

Currently, several methods and test instruments are available to determine the typology and resistance capacity of soils. However, in some cases, it becomes impracticable to carry out traditional tests due to logistical difficulties, human or financial factors. The guiding idea of the present research was the production of electromechanical equipment that would allow compression tests directly on the ground, providing reliability in the results in restrictive situations. In other words, a search for solutions to the problem, that is, the existence of a specific equipment and method capable of being used inside foundations for soil strength inspections. The development and results obtained with this Thesis are committed to some methods, processes and technological apparatuses of analysis and verification of soils whose purpose is to obtain data and information from the terrestrial surface on which all human activities are based, from dwellings to huge industrial parks. In this way, a scientific investigation was carried out for the adoption of new test procedures as well as the construction of new electromechanical equipment to complement the existing tests. The Thesis focused on comparisons of the data collected with some methods commonly used in Brazil, such as the test SPT and the Plate Test with a view to assisting, streamlining, complementing and qualifying soil resistance inspection work carried out by geotechnical engineering in shallow foundations, footings, rafts and compacted bases and possibly in foundation tubes. The tests carried out in the laboratory on undisturbed samples, precise and delicate, cannot be replaced by penetration methods, however, in conditions of laboratory impossibility, if used within the good technique, the penetration tests constitute an important tool for the recognition of the soils. Specifically, the objective of this work was to carry out the collect data on the loads and the respective displacements of the soil resulting from loads progressively applied to foundations and compacted bases, that is, to test, analyze and compare the loads and displacements resulting from the adoption of incremental load directly on the base of foundations with other consecrated methods of checking soil resistance. The introduction of new procedures through the equipment will allow immediate results to be obtained and support the team at the workplace, execution of a greater number of tests at the construction site, automation of tests and consequent reduction of possible human errors, issuance of performance reports computerized in time and immediate release of the foundation for the subsequent stages of execution. Introduces in the field of geotechnics another alternative for complementary verification and corroborates the agility and qualification of the analysis and determination of the resistance capacity of the soils since it will allow an important scientific advance in the works of construction in addition to laboratory teams that will be able to carry out better quality controls of their tests. Consequently, greater agility and support in tests is expected, especially in peculiar situations and in places of greater logistical complexity. Eventually, the equipment can be used in risk areas or in emergency situations, specifically, in the regions of the country where situations of collapse of the surface of the soil have been presented or may present themselves due to climatic effects, undue overloads, inadequate foundations or executions without technical assistance.
