In order to investigate the sensitivity of influencing factors of rock-socketed piles’ vertical bearing capability. The field static load test of embedded rock piles was performed in the article, and the pile-soil interaction model was built using ABAQUS software. The orthogonal test is properly designed to examine the sensitivity of the influencing elements of embedded rock piles by varying the relevant pile, pile side soil and bedrock parameters. The conclusions are as follows: (A) From large to small, the following factors have varying degrees of influence on the bearing capacity of rock-socketed piles: rock internal friction angle, pile diameter, rock elastic modulus, pile elastic modulus, rock poisson's ratio, soil density, soil thickness, rock-socketed depth, rock friction coefficient, rock cohesion, pile density, soil poisson's ratio, soil friction coefficient, soil elastic modulus, rock density, soil cohesion, pile poisson's ratio and soil internal friction angle; (B) Rock internal friction angle, pile diameter, rock elastic modulus, pile elastic modulus, rock poisson's ratio, soil density, soil thickness, and depth of the rock-socketed piles all have a greatly significant impact on the vertical bearing capacity of these piles. The bearing capacity of rock-socketed piles is significantly impacted by the rock friction coefficient and rock cohesiveness. The research results can provide a basis for the design of rock-socketed piles and the prediction of bearing capacity of rock-socketed piles.
