摘要
针对钢管桩高频振动沉桩研究和应用不足的问题,提出了ABAQUS有限元建模数字模拟分析的研究方法,并通过计算机模拟分析钢管桩高频振动沉桩的可靠性。该方法可有效分析钢管桩高频振动沉桩过程中的土体动力响应。结果表明,距管周1 m处土体径向的位移极值为6.5 mm,而距离管周3 m处土体径向的位移极值为2.3 mm,钢管桩高频振动沉桩对周边土体的影响局限在较小范围内,沉降影响可控。
In view of the lack of research and application of high frequency vibration pile sinking,ABAQUS finite element modeling digital simulation analysis method is proposed,and the reliability of high frequency vibration pile sinking is analyzed by computer simulation.This method can effectively analyze the dynamic response of soil during the process of high frequency vibration of steel pipe pile.The results show that the extreme value of radial displacement of soil 1 m away from the circumference of the pipe is 6.5 mm,and that of soil 3 m away from the circumference of the pipe is 2.3 mm.The influence of high-frequency vibration of steel pipe pile on the surrounding soil is limited to a small range,and the settlement effect is controllable.
