2026-09-24 Experimental and Numerical Simulation Study on Horizontal Bearing Capacity of Sand Foundation Reinforced by Polymer Sand Pile Group doi:10.57760/sciencedb.013th en This dataset presents the experimental and numerical simulation data for the manuscript "Mechanical behavior and reinforcement mechanism of polymer-stabilized sand pile groups under horizontal loading". The experimental data were generated through indoor model tests conducted in a custom 1 m × 1 m × 1 m box filled with Longyan sandy soil, using a pulley system for horizontal loading and a geotechnical data acquisition instrument for monitoring. The dataset includes load-displacement curves, pile strain records, and soil stress data for single, double, and triple pile configurations, as well as shear strength parameters of polymer-sand mixtures with varying polymer contents (0%, 15%, 20%, 25%). Numerical simulation data were produced using ABAQUS, containing model input files and output results for different pile numbers and arrangement patterns (parallel, perpendicular, and equilateral triangular). All data are provided in standard formats (Excel, CSV, and ABAQUS input/output files) with a README file describing the file structure, units, and experimental conditions. No missing data were encountered, and measurement errors were within the standard accuracy of the calibrated instruments. These data support the analysis of horizontal bearing capacity and reinforcement mechanisms of polymer-stabilized sand pile groups.
