| 摘 要： | 利用拉格朗日方法,将桩体复合地基分解为桩体、土体和桩土界面3个分离式单元,模拟了非均质地层中复合地基各种应力的分布,以及3个单元的相互影响及响应机理。结果表明,复合地基各种应力的分布受承台大小、桩体间距,及其弹模、土体的性质等多种因素的控制。

| Abstract: | In this paper, using Lagrangian analysis method , the composite foundation with piles has been analyzed as three elements apart: the pile, the soil and their interface. And then,the distribution laws of the stresses in inhomogeneous strata and the mechanism of the three elements impacting on and responding each other have been researched. The result shows that the distribution laws of the stresses are controlled by many factors, such as the scale of the caps, the space and the elastic modulus of the piles, the nature of the soil and so on. |
