USO E CORRELAÇÃO DE ENSAIOS DE SOLO IN SITU: CPD, CPE E LWD

comuns e menos dispendiosos, tais como o Cone de Penetração Dinâmica (CPD) e o Cone de Penetração Estática (CPE), e estabelecer correlações para a obtenção dos bons parâmetros. Neste estudo, realizou-se ensaios LWD, CPD e CPE, com solos do tipo A-2-4, A-6 e A-3, em um recipiente de dimensões determinadas, a fim de estabelecer correlações. Porém, conclui-se que é preciso ampliar a investigação geotécnica para melhorar a acurácia dos resultados encontrados, visto que não houve correlação com mais do que 63% de significância. ABSTRACT: The use of in situ tests is essential for the development of geotechnical works, as they allow to know the real conditions of support and soil condition. However, obtaining good geotechnical parameters requires the use of technological, complex and, consequently, expensive tests, such as the Light Weight Deflectometer (LWD). In the search for cost reduction, it is possible to use more common and less expensive tests, such as the Dynamic Cone Penetration (DCP) and the Static Cone Penetration (SCP), and to establish correlations to obtain the good parameters. In this study, LWD, CPD and CPE tests were performed, with soils of type A-2-4, A-6 and A-3, in a container of determined dimensions, in order to establish correlations. However, it is concluded that it is necessary to expand the geotechnical investigation to improve the accuracy of the results found, since there was no correlation with more than 63% of significance
