RADDATZ, Dennis; ARAYA, Cesar  y  TAIBA, Oscar. Results and numerical modelling of Osterberg cell load testing in Concón, Chile. Obras y Proyectos [online]. 2014, n.16, pp.33-39. ISSN 0718-2813.  http://dx.doi.org/10.4067/S0718-28132014000200002.

The operation of an Osterberg cell O-cell used for testing piles with large load in the axial direction is explained. Its main advantage is that it does not require the application of a load on top of the pile. The capacities are obtained for shaft and tip directly and separately. This paper shows the background and results of a series of tests performed with O-cell in foundation piles of great size in the Concón refinery. The data recorded in the field were used to calibrate a numerical model of the test using the finite element software Plaxis 2D. Finally, it is performed a numerical model of a traditional load test, which is compared to the equivalent curve for a traditional test carried out with the data of the executed O-cell load test.

Palabras clave : Osterberg cell O-cell; piles; bidirectional load tests.
