Abstract

This project studies the behaviour of continuous flight auger in a sedimentary soil, submitted to static compression loading tests. There will be two different locals to be analysed, CFA lengths varying between 10 and 13m. The whole process will be instrumented, and the instrumentation consists of electrical strain gages sticked to steel bars, installed in different levels along the CFA. CFA are becoming more and more important in construction field in Brazil, for medium and large works. Because of that, researches that can help to understand the interactions soil-pile are considered really relevant. This research will analyse two different static compression-loading tests, in order to obtain some parameters to analyse this soil-pile relation. After that, it will be possible to obtain the load x settlement and load transferring curves, in order to compare the obtained results with theoretical and semi-empirical methods. This research has the main purpose of helping the academic community to obtain and analyse project parameters in a way to get more reliable and efficient results. (AU)
