About the structural deformation and internal force characteristics of double-row piles in high retaining soil environment,we apply the numerical calculation and engineering observation methods,and analyze the deformation and force patterns of structures at different pile paths and different excavation depths.The results show that the maximum displacement of the front row piles with different excavation depths presents a secondary parabola when the pile spacing is taken 3 times the diameter of the pile.The internal force of the front pile presents the force characteristics of the single anchor board pile and the internal force of the rear pile presents the force characteristics of the cantilever board pile.The deformation and internal force of the structure can be controlled effectively by setting the unloading plate and using the material backfill with high shear strength.
