Аналіз параметрів грунтової основи, армованої грунтоцементними палями з використанням золи винесення

Abstract

This paper presents the results of numerical studies of the parameters of the base, reinforced with soil cement piles using ash. For the mathematical modeling of the work of reinforced-cement piles of the basis of the foundation of shallow laying the software product Plaxis 3D was chosen, which is based on the use of the numerical finite element method. In the study, the variation of the module of deformation of reinforcing elements from soil cement with addition of fly ash in the range from 100 to 2000 MPa is envisaged. Due to the reinforcement of the foundation by vertical soil cement elements, the deformation module of the foundation increased by 60-70% for piles arranged by blending technology, and more than twice for piles arranged by jet cementing (Jet Grouting). Accordingly, the design resistance was doubled for piles arranged by blending technology and more than three times for piles cemented with jet cementing (Jet Grouting).
