| 摘 要： | 提出了一种将有限元法和荷载传递法结合起来的桩基分析方法—有限元—荷载传递联合法。该法采用通用有限元程序ABAQUS实现了桩基竖向承载性状的计算分析。该法能非常简单地变化材料的本构关系和桩侧荷载传递函数。算例表明该方法计算结果可靠。对做过单桩静载试验得出单桩荷载传递规律的群桩,采用本文方法具有明显的优越性。

| Abstract: | A pile foundation analysis approach that combines both the finite element and load-transfer methods is presented.The approach can be used to fulfill calculation and analysis of vertical bearing characteristics of pile foundations with the universal program ABAQUS in the finite element method and can very easily change material constitutive relationship and pile-side load transfer functions.Numerical examples demonstrate that calculation of the bearing characteristics of the foundations with the approach is reliable.For group piles whose single pile went through static load tests and obtained with load transfer laws,the approach in question proves to have obvious advantages. |
