摘要
提出了分析堆载对邻近桩基影响的简化弹性地基梁模型,并针对实际工程,与二维有限元计算结果进行对比,分析了该方法的可行性,讨论了地基反力系数对计算结果的影响,确定了地基反力系数的取值方法。
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.
