abstract = {In order to study the influence of various factors on the bearing characteristics of super-long embedded rock piles, the bearing characteristics of ultra-long rock socketed piles is analyzed based on on-site static load tests. A three-dimensional finite element numerical model is established with FEA software and compared with the static load test to verify the feasibility of the numerical simulation; The influence of the factors, including pile length, pile diameter, embedded rock depth, pile-soil elastic modulus ratio and bedrock elastic modulus, on the bearing characteristics of the embedded rock piles is analyzed by changing the properties of the pile body and the soil body with the finite element software. The results show that: These five factors can improve the bearing capacity of super-long embedded rock piles to a certain extent, and the effects of embedded rock depth, pile-soil elastic modulus ratio, and bedrock elastic modulus on the bearing capacity of embedded rock piles should not be neglected except for the pile length and pile diameter.}
