Aiming at the calculation method of internal force of high-pile wharf without beam，we analyze the internal force of the high-pile wharf without beam,and study the distribution coefficient of horizontal concentration.Using the ANSYS finite element software for numerical simulation,we obtain the distribution coefficients of the horizontal concentrated force in the high-pile wharf without beam with different span and bay spacing.The results show that the distribution coefficients of the horizontal concentrated force in the bents of high piled wharf without beam are less than the normative values.The minimum deviation between the two is 1.8% and the maximum deviation is 39.6%.The horizontal distribution coefficients are essentially increased as the space between transverse bents increases.The distribution coefficient of horizontal concentrated force decreases when the number of along-longitudinal span or the number of along-transversal span increases.
