Abstract

Abstract

Stability analysis of pile group in soft soil foundation is one of the difficult issues challenging geotechnical engineering. According to Energy Balance Principle, the equilibrium relationship among dissipation energy caused by additional stress (including excess pore water pressure) in penetration process, external work and Elastic Potential Energy is established, based on mechanical analysis of the whole process of pile group penetration test in soft soil foundation, combined with pile group effect and working performance of pile group. Meanwhile, quantitative expressions of potential energy of excess pore water pressure, soil-compacting dissipated energy, work of gravity, work of excess pore water pressure, friction energy dissipation and elastic potential energy of soil are given in accordance with the soil-compacting characteristic of pipe pile prestressed high strength and current code of pile foundation design, and energy dissipation model of PHC pile group in penetration process is constructed. Furthermore, the safety factor of local energy and total energy is derived on the basis of above-mentioned work. The reliability of the energy model is verified by its application to the stability analysis of PHC pile group foundation in a project and the comparison with the numerical simulation results, which is of significance for guiding discrimination of the stability of PHC pile group in soft soil foundation.
