Based on the traditional static loading tests of piles for Zhengzhou Road-rail Bridge located in the middle and lower reaches of the Yellow River alluvial plain, finite element software ABAQUS was adopted to simulate the nonlinear performance of a large number of long piles with different lengths in the region. The limit lengths of piles with typical diameters in the region were obtained from the simulation. The simulated results are in good agreement with the test results, indicating the reliability of modeling method, selection of technical parameters and conclusions.%基于黄河中下游冲积平原郑州公铁两用桥桩基传统静载试验,采用有限元软件ABAQUS对大量常用桩径不同桩长的深长桩进行非线性数值模拟,根据模拟结果给出该地区几种桩径的极限桩长取值.模拟结果与试验吻合较好,说明有限元的建模方法、参数设置及结论可靠.
