桩径和端形对粗粒土破碎的模拟分析

摘要

Based on the two-dimensional granular flow theory,adapts crushing rule,the paper undertakes the discrete element simulation in the pile sinking process with different pile points and pile diameters,undertakes the detailed analysis and research on the pile surrounding foundation soil granular and its macroscopic influence on pile sinking,and has some meaningful conclusion.%基于二维颗粒流理论，采用特定的破碎法则，对不同桩尖形状和不同桩径的沉桩过程进行了离散元模拟，对桩周地基土颗粒的破碎及其对沉桩的宏观影响进行了详细的分析研究，得出了一些有意义的结论。
