摘　　要：采用数值方法对高频液压振动锤沉桩进行轴对称动力分析。在不考虑孔隙水压力情况下模拟沉桩的贯入过程,分析打桩力作用下应力的传播以及在桩体与土层的值与分布,并且考虑对高频振动沉桩影响因素,包括振动锤、桩体、土体的各种参数。The vibratory- driving technique to install piles affected the soil differently than traditional methods such as impact driving. And the shaft resistance of vibratory - driven piles was drastically reduced comparied with impact driven piles. Numerical analysis method was used to research the vibro -driveability without taking into account of pore pressure. Influencing factors were analyzed in details.
