近年来，随着城市基础建设的高速发展，静压桩以其振动小、噪音低、对环境影响小等独特的高质、高效的绿色施工特点，越来越受到工程界重视。本文采用室内模型试验的方法对静压桩进行研究。用特制的加力杠杆施加桩顶荷载，通过贴置在模型桩身的应变片和其他量测设备对模型桩的侧摩阻力、侧向压力等桩身应力进行了测量。在数据处理方面，本文提出了一种新的桩身应力计算方法，测量桩在压入程中的桩身应变，然后运用弹性力学方法得出桩侧摩阻力、侧向压力等桩身应力变化情况，为分析桩基础在压入过程中的力学性能提供了有力支持。

With the rapid development of urban,the engineers attach importance to jacked pile in these years, because of its merits of little quiver, low noise and little damage to environment.The model tests on jacked piles were designed to investigate the mechanical mechanism during the process of pressing pile and the bearing capacity of the pile.The pile side friction and lateral pressure of single pile have been measured by installing strain gauges and other measuring equipments.The elasticity method has been used in this paper to investigate the pile side friction, lateral pressure, and the changing of the pile side friction in the pile loading test to provide the powerful support for me-chanics performance of pile in the process of driving.
