摘要
群桩效应是桩基理论中的一个重要问题。文章利用大型通用有限元程序ANSYS,进行数值模拟研究,主要分析群桩与单桩在桩侧摩阻力、承载与位移等方面的不同,同时对群桩基础中不同部位桩的应力场位移场进行更深入的研究,为揭示群桩基础的作用机理提供了技术支持。
Based on three groups of numerical tests, the paper mainly analyses the differences between the single pile and pile group from the perspectives of skin friction, bearing and displacement and, at the same time, makes a further research into stress field and settlement field in different position piles in pile group, providing a technical support for revealing the working mechanism of pile group composite foundation.
