| 摘 要： | 在实际工程分析中用有限元法模拟无限域需要考虑很大一部分桩周土体来保证计算的精度,从而导致计算量的增大,同时对计算机的要求也很高。特别是对于大规模的群桩问题,有限元的计算工作量使一般的计算机无法满足其要求,这就限制了其在实际工程中的应用。本文基于叠加原理用有限元法计算桩-桩位移相互作用系数,不仅能减少群桩的计算量,又能提高计算精度。

| Abstract: | A finite element method was used to ensure the accuracy of calculation used to simulate the infinite domain of a large portion of soil around piles.In the analysis of a practical project,a lot of computer time was required to run the analysis.In the case of large scale pile group problems, a standard computer has been unable to meet the requirements of the finite element calculation, which limits its application in practical engineering.The finite element method was used to calculate the interactive coefficient of pile-pile interactions.On the basis of the superposition principle, the proposed method is expected to be applicable to the calculation of large pile group.The method can not only reduce the amount of calculation time for a pile group problem but also can improve the accuracy of the calculation.Conversely,the piles were simulated by beam elements to consider the engineering characteristics of piles under horizontal loads. |
