EN The objective of the present paper is to analyse, by means of combined experimental investigations and numerical simulations the load settlement response of axially loaded jet grouting columns with the aim of defining a theoretical methodology for the design of jet grouting reinforced foundations. The results of awell documented experimental campaign including full scale axial loading and pull-out tests on different jet grouting columns are first presented together with preliminary investigations. Interpretation of the load settlement response is then performed by aback analysis with afinite element code. Adopted model allows interpretation of interaction between columns and surrounding soil and a back analysis of the load transfer mechanisms taking place along the shaft and the base of columns. This analysis has been conducted by focusing on the role of the characteristics of jet grouting columns.
PL Przedmiotem artykułu jest przedstawienie wyników analiz numerycznych, wykonanych dla kolumn iniekcyjnych obciążonych osiowo. Wyniki analiz numerycznych przedstawiono w połączeniu z wynikami próbnych obciążeń kolumn, w celu zdefiniowania teoretycznej metodologii dla projektowania zbrojonych fundamentów z kolumn iniekcyjnych. W pierwszej kolejności przedstawiono wyniki dobrze udokumentowanych doświadczeń wciskania i wyciągania kolumn iniekcyjnych wraz z wstępnymi badaniami. Interpretację krzywej "obciążenie - osiadanie" przeprowadzono wykorzystując analizę wsteczną z zastosowaniem elementów skończonych. Zaadoptowany model pozwala na interpretację współpracy kolumn iniekcyjnych z otaczającym je gruntem oraz analizę wsteczną mechanizmu przekazywania obciążenia przez pobocznicę i podstawę kolumn. Analizę numeryczną przeprowadzono z uwzględnieniem rzeczywistych wartości parametrów materiałowych kolumn iniekcyjnych.
