Features: This book is a valuable reference for scientific researchers, engineering technicians, and master's and doctoral students engaged in the research and practice of composite foundation. It conducts a systematic study on the load-bearing capacity of composite foundation, a topic of great theoretical and practical significance. Based on a comprehensive analysis of the factors influencing the load-bearing capacity of composite foundation and the mechanisms of various composite foundation types, the book summarizes and derives analytical calculation methods for the load-bearing capacity of composite foundation. It also derives analytical formulas for the consolidation calculation of granular pile composite foundation that can consider well resistance and smear effects, establishes a unified numerical analysis method for calculating the load-bearing capacity of composite foundation, and focuses on introducing the three-dimensional finite element-boundary element coupled nonlinear analysis program FNIJ3D, which reflects the main influencing factors, main reinforcement effects, and actual load-bearing characteristics.
Using the numerical methods proposed in this book to calculate the P-S curves of crushed stone pile composite foundation yields results that are highly consistent with field measurements. The results obtained for flexible pile composite foundation and rigid pile composite foundation comprehensively reflect the load-bearing characteristics of various composite foundation types. The numerical methods presented in this book include functions such as inverse analysis of soil properties, simulation of load tests of various sizes, and optimization of design parameters. The combination of these methods with practical experience will provide an effective approach for further research on the load-bearing capacity of composite foundation. Additionally, this book provides the source code for three-dimensional numerical simulation research and calculation of composite foundation.
