Characteristics and Application Potentials of Ground Improvement with Semi-Rigid Inclusions Based on an Innovative Composite of Polymers and Gravel-PPT Presentation

PPT Presentation

Pdf Summary

The presentation, delivered in Berlin on 20 May 2022 by Univ.-Prof. Dr.-Ing. Conrad Boley, examines ground improvement using semi-rigid inclusions made from an innovative composite of polymers and gravel. The material is positioned between flexible stone columns and rigid concrete elements.<br /><br />Image-processing and segmentation methods are used to assess the consistency of laboratory samples and evaluate in-situ ground improvement through drill cores. The research also applies standard soil and rock mechanical tests alongside rheological testing of the polymers. Results indicate that a 10°C temperature increase significantly affects the polymer reaction rate and the time required to reach initial strength.<br /><br />Plaxis 3D numerical simulations compare stone columns with composite columns, considering their role as vertical support elements and the contributions of side friction and lateral confinement.<br /><br />Further details are provided in the paper “Characteristics and Application Potentials of Ground Improvement with Semi-Rigid Inclusions Based on an Innovative Composite of Polymers and Gravel.”
