摘　　要：分别从力学、运动学、能量守恒方程和运动规律的积分方程等方面进行阐述,总结了国外各种高频液压振动锤打桩的可打入性模型的相应原理、假设条件、判断方法及应注意的问题,最后指出了欲进一步预测高频振动锤打桩的可打入性应考虑的几个问题。To provide standards or guidelines related to the driving of piles with vibratory hammer, a series of driveability models are studied to determine the parameters of vibratory hammers, piles and soil and their interaction. The focused aspects include the principle, presumptive conditions, judgement methods and difficulties, which are classified in terms of mechanics, kinematics, equations of energy conservation and integration of motion law. The aspects to consider in using the vibratory hammer are proposed.
