摘要
垫层是组合桩复合地基的重要组成部分,为了分析垫层的厚度、弹性模量等参数发生变化对复合地基工作性能的影响,采用有限元分析软件ANSYS对不同厚度垫层下组合桩复合地基单桩的工作机理进行了数值模拟.对垫层的作用进行了分析和探讨.初步分析表明,垫层改善了复合地基的工作性能,提高了地基承载力.
Cushion is an important constitute of Combined Piles Composite Foundation, in order to analyze the influence of work character that led by the changes of cushion thickness, modulus of elasticity, etc. By using the large-scale FEM software ANSYS, the data simulate to the working behavior of combined pile composite foundation with different thickness of cushion were made, and the effect of cushion were analyzed and discussed. The calculated results indicate that the cushion has a positive impact on the work characters of composite foundation.
