Abstract

This study shows Finite Element calculations of a swelling soil improved by resin injection technique. Several buildings show cracks which are often caused by swelling clays on which the structures are founded. To overcome the problems associated with the swelling layer, it was decided to improve it by injecting stabilizing expansive resins. The in situ mechanical properties of the soil were investigated using the pressuremeter test. The current abstract summarizes how to model and predict the effect of resin injection on the soil behaviour by making use of ERT as a guide. For the numerical modelling, the Finite Element model has been selected, and the most advanced constitutive models available for geotechnical engineering have been adopted. The proposed procedure therefore is an integrated use of ERT, standard geotechnical testing and Finite Element modelling and can be extended to any other case where it is important to feed the analysis results with field data in almost real time.
