The Standard Penetration Test (SPT) is often used to estimate the soil parameters for geotechnical design projects, using the NSPT index. However, these estimates are performed based on empirical correlations without any scientific basis. Moreover, the test has a large inherent results dispersion due to the us...

In the design of piles drilled in rock, the following questions arise: (i) at what point of the soil/weathered rock/sound rock profile should the pile socket be designed; (ii) is the contribution of residual soil to be disregarded; (iii)how much consideration should be given to the pile boring method (rotary or hammering). Furthermore, usual design meth...

A case study on the application of the parallel-seismic (PS) and induction-logging (IL) tests combined to evaluate the depth of a 25-cm diameter root-pile belonging to the foundations of a telecommunication tower located in Santana de Parnaíba, São Paulo, Brazil, is presented. The foundation element is embedded ...

The evolution of numerical modelling in rock mechanics has made possible a more realistic representation of the behaviour of rock masses, and a more reliable prediction of the response of rock engineering structures. Discontinuum modelling techniques, namely the discrete elemen...
