LeVoresT -  Model test, numerical calculations and development of the design concept

The LeVoresT joint project is dedicated to the development of an efficiency-enhanced full displacement bored pile system as a resource-optimized deep foundation element in order to exploit the great untapped potential for increasing load-bearing capacity and thus saving material and resources in such pile systems. The basis is the first-time combination of scaled model tests, numerical in silico investigations and practical validation in large-scale field tests in this context. At the same time, a scientifically valid and accepted design approach is to be provided, making the savings in reinforced concrete associated with the increase in load-bearing capacity of ≥ 25% accessible to construction practice. The sub-project of the University of Siegen initially aims to design and build a test rig including model tools and measurement concept and to carry out scaled model tests on established and optimized piles. In parallel, the university is developing a numerical finite element model based on the CEL approach and validating it with pile test load data for established full displacement bored pile systems. On this basis, optimized pile variants are modeled and the most promising variants are investigated in model tests. This leads to the selection of the pile modifications for the large-scale test together with the partners. Further focal points of the sub-project include the monitoring and scientific evaluation of the large-scale tests, the subsequent investigation of the increase in load-bearing capacity achieved from model and large-scale tests as well as the numerical simulation and, based on this, the development of a standard and regulation-compliant design concept. A comprehensive sustainability analysis will also be used to prove the effectiveness of the pile optimization in terms of CO2 savings, among other things.
