摘要：
A method to calculate the settlement of pile foundation based on the results of vertical static load test of single pile and the elastic theory method was presented. In the method, the settlement of every pile due to its own vertical load was determined by the settlement-load curve of vertical static load test, while the settlement caused by other piles was calculated with the elastic theory method based on the test result of side friction curve and toe force of pile. Tentative calculation was performed on the different vertical forces of each pile to find out the solution. that met the equilibrium equation of pile cap and the coordination conditions of the settlement of each pile. Following the theory, corresponding calculation formulae were constructed and calculation program was compiled. Finally, the settlement of the pile foundation of a bridge was calculated with the method and the better agreement of the results between the calculation and in-situ measurement proved the feasibility and rationality of this method. © 2017, Editorial Office of Journal of the China Railway Society.
