Hydraulic pile hammer is one of the pile driving machines that drive prefabricated piles into the ground in the construction of pile foundation such as construction, bridge, dock, etc.

液压打桩锤是用于建筑、桥梁、码头等桩基础施工中打入预制桩的桩工机械。

During driving a pile, the soil around the pile will be disturbed by the repeated hammer loading, which cause the soil strength to decrease greatly.

在动力沉桩过程中，桩长时间连续运动导致桩侧土体强度的降低，使土体产生疲劳效应。

Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of driving pile.
