The parallel seismic method for foundation depth evaluation: a case study in Arthur Alvim, São Paulo, Brazil

Abstract:

A case study on the application of the seismic test of recent use in Brazil, called Parallel Seismic (PS), to evaluate the depth of a 250-mm diameter root-pile belonging to the foundations of a telecommunication steel monopole located in Arthur Alvim, São Paulo, Brazil, is presented. The foundation element is inserted in a sandy clay soil. The estimated depth of the foundation element was obtained by analysis of the results from the PS test. It was evaluated as being equal to 11 m, which was later verified to be in agreement with the pile’s design drawings. When the possibility to drill boreholes at a site under investigation exists, the method presented in this article becomes a good option for the determination of the unknown depth of foundation elements.
