摘要
基于内击沉管灌注桩的独特沉桩过程,建立了先静压后内击的沉桩颗粒流模型,将模拟结果进行分析,对桩贯入土体宏观与微观力学响应进行了研究.通过分析土体细观变化模式,揭示沉桩过程中宏观响应的内在机理.
Based on the pile- sinking process of the sinking pipe pile, established the particle flow model of static pressure before striking. The simulation results are analyzed, and the macro and micro mechanical response of pile penetration of soil are studied. Reveal the inner mechanism of the macroscopic response through the analysis of microstructure change pattern of soil.
