静力沉桩的室内模型试验装置研发

Development of laboratory model test equipments for jacked piles

摘要: 砂土中静力沉桩是一个复杂的过程，可以通过室内模型试验的方法对其机理进行探究。研制了一套功能完备的自动压桩仪。该设备通过伺服系统控制，具有恒力加载和匀速加载等特点，增加了控制精度。为试验提供了较为稳定的条件。

Abstract: It is complex for jacked piles driving in the sands. However, it can be studied by laboratory model tests. A fully functional automatic piling device has been developed. Through the servo control system, the device has the functions of constant force loading and uniform loading, and it may provide stable test conditions.
