Strauss Type Deep Foundations

The aim of this paper is to present the concepts and definitions of the main types of deep foundations and their implications for civil engineering, with reference to the requirements of current standards. Subsequently, the case study of the Strauss pile construction process, located in the municipality of Barbacena/MG, will be presented. We will then highlight the characteristics that make the use of Strauss piling feasible and its concepts, presenting the executive method that was technically monitored through visual inspections. Based on this, the study analyses the entire Strauss pile construction process, discusses the problems of execution errors based on the prescriptions of technical standards and presents systematic and rational solutions for its construction process. The results analysed point to a significant improvement in the productive and economic aspects of the execution stage, highlighting the importance of good supervision of the execution of Strauss piles, as well as the importance of the design, execution and supervision standards for Strauss-type deep foundations.
