Implication

Analytical modeling demonstrates accurate multi-interface load transfer in pipe-stiffened deep cement mixing piles, suggesting optimized design parameters for soft ground.

Key Points

To develop an analytical model that explicitly accounts for multi-interface load transfer and predicts the axial response and displacement of pipe-stiffened deep cement mixing (P-SDCM) piles.
Decomposed the P-SDCM pile system into the in-core DCM, precast pipe, out-core DCM, and three distinct interfaces governed by nonlinear softening shear models.
Developed a displacement-controlled iterative algorithm to solve for axial displacements, internal forces, and interface shear stresses.
Validated the analytical framework against physical laboratory tests and three-dimensional continuum finite-element simulations before performing parametric evaluations.
Accurately predicted the overall load–settlement behavior and load distribution among the constituent pile components.
Quantified the effects of geometric and material property variations on the axial load capacity to establish design optimization guidelines.
