| 中文摘要: |
| 本文将带桩的条形基础视作一整体，并假定群桩与条形基础的位移模式，然后将能量变分原理应用于分析桩-条形基础系统，用最小势能原理求解假定位移模式中的一系列参数，从而获得条形基础和群桩的沉降分布。应用本文方法同时可以得到条形基础各点的弯矩、剪力、桩身各处沉降及应力分布。本文方法与有限元计算结果吻合，且原理清晰，计算简单。 |
| 英文摘要: |
| The coupled system of pile group and strip type footing is assumed as an integrated structure.Based on the assumption on steelement mode,the principle of energy variation is applied to analyze the coupled system. Parameters of the settlement mode are deduced by using principle of minimum potential energy.Consequently the distribution of settlement is obtained.By this method the moment and shear stress of the strip footing at any position as well as the stress and settlement of the piles can be calculated. |
