| 摘 要： | 从单桩与桩间土的荷载-沉降曲线出发,采用荷载-沉降的双曲线模型,给出了多元复合地基桩土应力比的解析解。分析表明,桩土应力比随荷载的变化形式有3种,具体的变化形式与桩、桩间土的初始切向压缩模量和极限承载强度有关。实例计算表明,所得解析解与实测桩土应力比值基本吻合。 |

| Abstract: | The analytical solving of stress ratio between piles and soils for multi-element composite foundation is given by using the hyperbola model of load-settlement based on the curve of load-settlement of the single pile and soil.The paper discusses the effect of applied load upon the stress ratio between piles and soils.There are three types of n-p which are mainly concerned with the limited bearing capacity and initial tangential modulus.The results from the analytical calculation are found to be in agreement with that by actual solution. |
| Keywords: | multi-element composite foundation hyperbola model stress ratio between piles and soils initial tangential compact modulus limited bearing capacity |
