| 摘要: |
| 基于混合法的基本思想，提出了用于群桩沉降非线性计算的近似混合法。近似混合法通过构造单桩沉降荷载曲线的插值函数以及采用相互作用系数考虑群桩之间的弹性影响，避免了因各桩离散成许多单元而导致土体柔度矩阵[δs]集成的费时，从而可进行多桩数群桩的非线性计算而不受微机内存和运算速度的限制。算例证明，本法与混合法的计算结果非常吻合。 |

| Approximate hybrid method for computing the settlement of pile groups |
|
|
| Abstract: |
| Based on the principle of hybrid approach,approximate hybrid approach for the prediction of nonlinear settlement of pile groups is presented.It avoids dispersing piles to many elements by constructing interpolating splines of single pile and by using interaction factor to calculate the interaction between piles.It can be applied to piled foundations consisting of lots of piles without the limitation of computer speed and memory capacity.The Results calculated by approximate hybrid approach are more coincided with those calculated by hybrid approach. |
