| 摘 要： | 基于复合地基等应变条件下应力和位移的精确解,得到了桩土应力比、沉降比、径向位移和桩土侧压力系数等的计算公式。分析了它们随桩土压缩模量比和置换率的变化规律,并在分析过程中与Priebe法做了比较,详细分析了Priebe法中所做假设对计算结果的影响。分析表明,Priebe法中忽略桩体体积应变的假设会带来较大的误差,而针对径向变形计算和桩土侧压力系数的假定由于影响的相互抵消作用,其综合影响不一定很大。

| Abstract: | Based on the analytical solution of stresses and deformations for composite foundations with equal strain assumption,the expressions for stress ratio,settlement ratio,radial displacement and lateral pressure coefficient are obtained.The variations with the ratio of compression modulus and the ratio of area replacement are illustrated and compared with the Priebe's method.The influences of assumptions in Priebe's method on computational results are also analyzed in detail.The analytical results show that the... |
