| Abstract: | A non-linear numerical solution to a fourth-order ordinary differential equation was obtained by use of the spline method, which could be used to calculate the horizontal deflection and internal force of elastic vertical piles under any geological condition. Case study showed that the calculated result is of certain stability no matter how many nodes on piles under ground surface were selected for calculation. |

| Keywords: | elastic vertical piles coefficient of horizontal reaction force of foundation horizontal deflection (internal force) |
