Estudos sobre análise de risco em fundações por estacas

Abstract

The need to develop Engineering projects that combine safety, comfort and reliability, is becoming more and more present. It is of fundamental importance to consider that a civil work must meet safety parameters, but these are interconnected to other parameters, which evaluate the reliability of the enterprise. The present work makes a bibliographical study about the risk analysis of ruin in foundation works by stakes, considering the several variables involved in the elaboration of these projects, the soil variability, the executive process of each structural element of foundation, among other factors, emphasizing that these are subject to the action of random phenomena, becoming susceptible to ruin, which brings us to a probabilistic study of these phenomena. The work shows how important is the monitoring of the request loads and resistance loads of the structural foundation elements, from the study of the ground, the design exigence for each type of stake, and the techniques for proof of loads. In order to do so, it is necessary to understand some basic concepts about probability and statistics, especially about data adjustments through normal curves, besides the concepts about foundation works using stakes and the results obtained in the risk analysis, in order to be able to conclude the risk level that the work presents, which, in the case of the hypothetical example presented, resulted in an occasional risk.
