摘要

以一维应力波理论为基础,运用ANSYS/LS-DYNA显式分析方法,对脉冲荷载作用下的码头基桩完整性检测进行了数值模拟,并对得出的模拟结果进行信号处理,总结得出一种新的码头基桩检测方法。最后将数值模拟曲线与实测曲线进行对比,发现两者取得较好一致,表明数值模拟和检测方法是可靠的,对提高码头桩基检测结果的准确性具有较重要的意义。

Abstract

Based on the one-dimension stress wave theory, the integrity test of wharf pile under impulse load is simulated by ANSYS/LS-DYNA. Then one method of wharf pile test are induced by simulated signal processing. Finally, it’s shown that the simulated curves are in good agreement with those obtained from field measurements. Consequently, the numerical simulation and the method of wharf Pile test are correct and they will play an important role in increasing the accuracy of wharf Pile test.
