Practical Variational Analysis on Vertical Behavior of Jet Grouting Soil-Cement-Pile Strengthened Pile

Jet grouting soil-cement-Pile strengthened Pile (JPP) is a new kind of composite pile, and is a great ground improvement technology in soft ground. Based on the variational principle, the total potential energy of single JPP pile is established, and it is expanded to a simple equation of matrix form, in which a finite series is used to denote the vertical displacement of JPP. Load transfer function is used to describe the force-displacement relationship. In light of minimum potential energy, a practical method is obtained for the load-settlement relationship of single JPP pile. Using this practical method, the settlement of single JPP pile can be estimated quickly. Comparisons between results using this practical method and model test measurements indicate that the method can predict the performance of single JPP pile. Finally, factors of vertical behavior of JPP pile, such as slenderness ratio, ratio of pile head settlement to pile base settlement and Young's modulus of core pile and soil-cement pile, are analyzed.
