Analysis of the Effect of Surcharge Loads on Adjacent Piles for Bridge Abutment

An elastic foundation beam model was proposed to analyze the effect of surcharge loads on adjacent piles for bridge abutment.Compared with the result of 2D finite element method in an engineering case,the feasibility of the model was validated.The influence of the coefficient of subgrade reaction on the results was discussed,and the method to choose the value of the coefficient was established.
