Análise de tensões e recalques em uma estrutura enterrada

Abstract

There are several solutions to the foundation of a structure, whether buried or not. They are subdivided into deep and superficial, which are differentiated by geometric questions and the way of transferring the load to the soil. There are several methods of predicting the loading capacity and the settlement of deep and superficial foundations, which provide prediction of their behavior. From this information, it is possible then to predict the damages in which the structure will be submitted, be they aesthetic, functional or even structural damages. In the event of damage that might otherwise compromise the building, it is up to the designer to study a new geotechnical solution that is economically feasible. Thus, the objective of this work is to analyze the deep foundation of a buried rainwater reservoir, located in the city of Uberlândia / MG, estimating its load capacity, its settlement and the possible damages in which it is submitted. In order to do so, the soil tension was compared before and after loading of the reservoir, reaching the conclusion that the soil weight is higher than the weight of the reservoir. It could be observed that the permissible load capacity is much higher than the load, which resulted in minimum settlements and no damage to the tank. After that, it was proposed a superficial foundation for the reservoir, analyzing it in the same way, concluding that, if it is guaranteed to waterproof the reservoir, it is the best solution to be adopted, because the permissible load capacity, the limiting differential pressure are adequate and have the best cost-benefit ratio.
