群锚静载试桩研究

Study of static-load testing of pile with groups of bolts

应用全长粘结式锚杆群代替反力桩进行桩基静载试验,不但工艺简单、施工方便,而且工期短、成本低。通过对锚杆的力学分析和现场量测,获得了锚杆的受力和位移特征,为这类锚杆的设计与计算提供理论依据。

This study make use of the wholly grouted groups of bolts for static-load testing of piles instead of the counter-force piles, which is not only technically simple and convenient for construction, but also short in the period of project and economical cost of construction. Based on the mechanical analysis and the in-situ observations, the forcing and displacement characteristics of the bolts are obtained so as to provide the theoretical basis for design and calculation of this type of bolts.
