This paper presents a detailed description of the relative advantages and disadvantages of volume piles and embedded piles. The mesh dependency is more significant in an embedded pile. When a large number of piles have to be considered, the number of elements in the system is significantly reduced using embedded piles. The results obtained with both models were compared with the data obtained from full-scale loading tests in a case study of a driven pile followed by a micropilote, subjected to compression, tension and shear (case 1), and with the results of an elastoplastic analysis carried out with the well-established integral equation method (case 2). In case 1, the results of the pile subject to compression revealed that the volume pile can reproduce the step produced by a change in the section of the pile, something not possible with an embedded pile. For tension tests or lateral load, the embedded pile reproduces better the displacement measured in the head of the pile or the efforts along the shaft. The conclusions obtained refer mainly to the types of numerical modelling described in the text of the paper and to the programs in which they apply.
