A detailed research is done on the distribution coefficient of the horizontal force in the highpiled wharf using the finite element software ansys，focusing on the impact of vertical bents’distance and bent numbers on the distribution coefficient. It is modeled and analyzed in six different structures of 5 spans, 6 spans,7 spans, 8 spans, 9 spans and 10 spans and in five different distances of 5 m, 6 m, 7 m, 8 m, 9 m and 10 m respectively. The results show that the impact of the vertical bents’distance on the distribution coefficient is little with the maximum of 4.93%, while the bent number impacts a lot with the maximum of 49.6% for the calculation example in this paper. Reasonable suggestions are put forward to the analysis method of the large wharf structure with many spans and large bents, based on the comparative analysis of the most adverse bent distribution coefficient with the number in the standers.
