摘　　要：本文旨在探索一种可靠的基桩动测曲线数值模拟方法,在此基础上对基桩动测曲线做进一步的分析。文中介绍了基桩动测原理,分析了实体模型数值模拟的必要性。应用ABAQUS软件建立了桩土实体模型,计算得到相应的模拟曲线。归一化对比模拟曲线与模型桩动测曲线,发现两者有较好的一致性。通过ABAQUS模拟出大量数据,为进一步结合小波分析、神经网络、地层三维可视化研究基桩动测曲线提供了数据基础。In this paper,one kind of reliable numerical simulation for dynamic pile testing is to be explored,which provides a basis for the furthermore analysis of the curves of dynamic pile testing.The theory of dynamic pile testing is presented,and the necessity of numerical simulation for entity model is also analyzed.By using ABAQUS,the entity model is created and the related simulation curves are described.By contrast,the normalized curve of simulation is consistent with that of dynamic pile testing.Finally,a great number of statistics calculated by adopting ABAQUS supplies a basis for deeply studying curves of dynamic pile testing combined with wavelet analysis,neural network and 3D stratum visualization.
