Laboratory tests for the physical characterization of MSW, Standard Penetration Tests (SPT) and plate load test (PLT) were carried out in different time points, in an Experimental Cell and in the old existing landfill. Subsequently, based on the results of the PLT, the bearing capacity of the experimental cell and the old landfill was determined. The SPT did not reveal any tendency to increase or decrease in the penetration resistance index (NSPT) over time. The PLT showed a linear relationship between the applied pressure and the settling obtained with the plate was evident, in the experimental cell and in the old landfill, indicating the absence of the physical rupture in the mass of the requested waste. The effect of the fiber in the waste behavior could only be observed in the old landfill. In general, the old landfill had higher stiffness and bearing capacity than the experimental cell.

H. L.; Moura, A. S.; Silva Filho, F. C.; G. Filho, F. V. C.; Cerqueira Junior, E. Abstract: The prediction of deep foundation settlements remains challenging due to the scarcityofstudies about it. This paper aimed to evaluate the accuracy of the usage of load transfer methods in predicting the settlement of bored piles in granular soil in Brazil’s Northeast. For this, two small piles were installed and submitted to load tests, a small amount of expansive polystyrene was placed under one of the pile’s tips to evaluate the load distribuition of the elements.. For the settlement’s prediction, methods based on load transfer functions, such as analytical and numerical (using RSPile and UniPile ), were employed. The comparinson of the predicted values with the experimental measurements showed agreement in the elastic zone of soil’s behavior for all the methods. For higher loads, discrepancies occurred. The method proposed by Massad (1992) was the most effective among the used methodologies. Using the mentioned programs, results were close to the experimental values.

Therefore, estimates of load capacity and foundation settlements are necessary. It is usual to make these estimates based on the results of field trials. The present work proposes an evaluation of the predictions of load capacity and settlements of foundations on precast piles using semi-empirical and theoretical methods based on the results of percussion sounding (SPT), with and without consideration of the test efficiency correction. To this end, seven piles were analyzed, manufactured in reinforced concrete, and driven into typical soil profiles of the Metropolitan Region of Fortaleza (RMF). For the proposed evaluation, the results of load tests and SPT surveys were used. The predictions estimated by semi-empirical and theoretical methods were compared to the values obtained experimentally through load tests. The load capacity and settlement predictions were made without correcting the sounding efficiency and for an efficiency of 70%. Considering the correction of the efficiency of SPT soundings, both in load capacity and settlement calculations, promoted more consistent predictions for almost all situations analyzed.

The study describes the procedures of approximation between the university and the community, as well as the participation of the company responsible for the geotechnical tests and analyzes. The study aims to present elements that will enable the provision of guidelines for the more rational use of the local subsoil, the design and future execution of the foundations. Preliminary data allow the identification of the type of foundation to be adopted. The performance of ETecS (Office of Social Technology) makes it possible to provide a quality engineering service to needy communities and provide students with technical and citizen training.
