There are many mature methods to detect the bearing capacity of single pile

but for high-piled wharf piles

as they are parts of high-piled wharf

and complex structures are built on them

at this stage

for these non-free end piles

there are no effective and feasible bearing capacity detection methods. In this paper

regional heap load method to detect high-piled wharf piles capacity is proposed

and this method doesn’t destroy the original structure. The high-piled wharf piles capacity prototype testing is carried out

and the deformation displacement of while high-piled wharf

the displacement of piles

and the strain of structural elements are tested under grading loads. Also the numerical model is established to analysis the bearing capacity of high-piled wharf piles

and the numerical model is corrected by the experimental results

then the whole prototype test process is simulated using the modified mathematical model. The comparison between the numerical results and the experiment data shows a satisfactory agreement. Through comprehensive analysis

the vertical bearing capacity of high-piled wharf piles is finally determined as 1 400 kN

which could ensure the safety of the high-piled wharf

and the study results could provide experimental basis for the design of the wharf.
