In the present thesis, the comparative analysis is realized between accessions and theoretical and royal capacities of load in two projects: Bridge Fortaleza, located in Pativilca's district, province of Gully, Department of Lima and the Bridge Crisnejas located in the city of San Marcos, Cajamarca's Department. The diversity of soils in the two projects is a fundamental aspect for the analysis. In the case of the Crises bridge, two piles were analyzed in the right abutment and another in the pillar center in the ground where the pilot of the right stirrup predominates the clay of low plasticity in most of the strata, in the pilot of the central pillar has a heterogeneous soil starting with a Limo of low plasticity, then silty sand and finally a gravel poorly graded. In the Fortress Bridge project has a pilot in the left stirrup where there is a sample of the quality and appreciation of clay of medium plasticity, silt of low plasticity, silty sand and poorly graded sand. The theoretical calculations of load capacity and settlements were made using analytical methods based on theoretical principles of geotechnics which were applied according to the nature of the terrain as the type of terrain where the tip and the shaft are located. In the investigation, the following Vesic, Reese and O'Neil, Meyerhof, for cohesive soils and Vesic, Coyle and Castello, Janbu, Chen and Kulhawy and Berezantzev. The load capacity in the shaft was calculated by means of the friction contribution formulas of Coyle and Castello and by Adhesion the methods α, β and λ. Finally, the settlement calculation was developed by the proposed methods of Vesic and Bowles. The actual loads and settlements were obtained through dynamic load test (PDA) tests. This method is the most realistic to estimate the load capacity, because it provides information on the behavior of the applied stresses and the soil-pile interaction with respect to the results obtained from a static load test. Tables, to have the reliability of the same ones, verified the geotechnical parameters, obtained from the laboratory tests, for the calculations of the load capacity. The present thesis aims to obtain safety factors or correction factors to reduce the variability that exists between the loads and theoretical and real settlements in the Fortaleza and Crisnejas bridge projects. Finally, it was concluded from the investigation that the values obtained from the carrying capacity and settlements by analytical formulas s are in general conservative when compared with the values measured in load tests. The present thesis presents the results obtained when analyzing load tests in relation to design calculations, to establish which one or which of the design methodologies, is closer to the real values.
