Currently

there are few studies on inclined pile field test. Four piles at the position of 40 # and 41 # fans (two vertical piles

two inclined pile) were tested for their vertical bearing capacity in Donghai Bridge Wind Farm Phase II project. Prior to testing

the ABAQUS was used for preliminary analysis on vertical piles and inclined piles under reasonable conditions and selected soil parameters. it found that the calculated results and post-test results are close

and after comparing calculated results and the results of test piles

it showed: 1) at the project site conditions

finite element analysis and experimental results showed that the vertical ultimate bearing capacity of inclined pile was less than vertical ultimate bearing capacity of vertical pile. 2) when the inclined pile was under axial load

the settlement and the settlement value range on the anticline side of the soil were significantly greater than that on the oblique side; 3) the finite element analysis and the parameter value were more reasonable

which could provide reference for similar project preliminary analysis; 4) ultimate bearing capacity of the two vertical piles was less than design value: ultimate bearing capacity of the two inclined piles was greater than the design value; the proportion of pile side resistance of the two inclined piles was higher than that of two vertical piles; the proportion of pile side resistance was lower than two vertical piles.
