In-situ lateral load tests were conducted on rectangular piles in gravelly soil before and after grouting to investigate the impact of combined side and end grouting on lateral bearing capacity and the failure mode of pile-soil interaction. The results indicate that this combined grouting technique significantly enhanced the lateral bearing capacity of the pile, achieving a 30% increase compared to before grouting. After grouting, the bonding state between the pile and the soil improved, resulting in the formation of tension-shear cracks within the soil on the side of the pile under lateral load. The load-displacement curve of the rectangular pile exhibited nonlinearity, with the deflection deformation showing the load characteristics of an elastic long pile. The bilinear model can accurately assess the actual bearing capacity of the rectangular pile. Comparing the theoretical model predictions with the experimental data, the prediction errors were -3.5% and 1.8% before and after grouting, respectively.
