Experimental research programme on the behaviour of a pile group in a homogeneous base
Abstract
Introduction. A programme of experimental research based on numerical modelling of pile group behaviour in a homogeneous sandy foundation is considered. The relevance of this work is due to the need to improve the reliability and safety of pile foundations, which are widely used in modern construction. The research is aimed at eliminating the existing gaps in predicting the interaction between piles and homogeneous soil. Within the scope of this study, a comprehensive experimental programme was developed and tested, including both modelling and field tests. The results obtained allowed us to propose new approaches to the calculation of pile groups, which has significant scientific and practical value for the construction industry.Materials and methods. Data from scientific publications, regulatory documents, project materials, and experimental results were used. Methods of systematic analysis, modelling, as well as experimental and statistical approaches, were applied. These methods enabled the acquisition of new data and adjustments to the calculation methods for pile foundations.Results. A numerical model for experimental research was developed, various calculation methods for pile foundations were analyzed, a test stand model was created, and a step-by-step experimental programme was designed.Conclusions. The research results on the behaviour of pile groups in a homogeneous foundation have high scientific and practical value. The developed mathematical model and experimental data allowed to describe more accurately the distribution of loads and deformations in the pile group, which is a significant contribution to the theory of calculation of pile foundations. The obtained results confirm the necessity and importance of revising the existing methods of pile foundations calculation. Their introduction into construction practice and educational programmes will improve the reliability and efficiency of construction, as well as create a basis for further research in this field.
