恒定荷载下拉力型锚杆系统界面流变实验特性分析

An analysis of the tensile type anchor system interface characteristic rheological experiments under constant load

针对已经达到应力平衡的锚固系统开展锚固界面流变试验,验证了锚杆系统的4种破坏形式。锚固系统界面的流变过程主要经历初始、稳定和加速流变3个阶段,通过流变速率曲线可直接判定锚杆系统的界面流变状态。

More and more attention has been paid to the anchorage system rheology in geotechnical anchoring.Researches have been made for anchoring the mechanical properties of interface,and theory and tests of the anchoring interface shear stress distribution are obtained. But the rheology of anchorage interface of anchorage system is seldom examined to be a balanced stress influence. Based on the modified experimental device and system,in view of the anchoring interface rheology in anchorage,the interface rheological test is carried out and the anchorage system interface of rheological properties and rheological state standard are obtained. The results are of great realistic significance to adding the anchor rock mass stability control.
