为了研究充气膨胀控制锚杆在长期荷载作用下的力学性能，在室外天然场地对充气膨胀控制锚杆进行蠕变试验。通过陈氏法对试验数据进行处理，绘制位移-时间曲线、等时荷载-位移曲线与刚度回归曲线，分析得出了充气膨胀控制锚杆的蠕变规律。结果表明：在同等气压作用下，当施加荷载低于其极限抗拔承载力的40%时，充气锚杆基本不会发生蠕变；充气锚杆在不同气压作用下的蠕变特征不同，低气压时仅经过减速蠕变和稳定蠕变两个阶段，气压较高时会经过减速蠕变、稳定蠕变和加速蠕变共三个阶段；引用Burgers模型，并利用等时曲线法和过渡蠕变法得出充气膨胀控制锚杆的长期抗拔承载力为其极限抗拔承载力的65% ~ 75%。

In order to study the mechanical properties of aerated inflation controlled anchor under long-term load, the creep test of aerated inflation controlled anchor was carried out in outdoor natural site. The test data were processed by Chen's method, and the displacement-time curve, isochronous load-displacement curve and stiffness regression curve were drawn. The creep law of aerated inflation controlled anchor was analyzed. The results show that under the same air pressure, when the applied load is less than 40% of its ultimate uplift bearing capacity. The inflatable anchor basically does not creep. The creep characteristics of inflatable anchors under different air pressures are different. At low air pressure, there are only two stages of deceleration creep and stable creep. When the air pressure is high, there are three stages of deceleration creep, stable creep and accelerated creep. Based on the Burgers model, the long-term uplift bearing capacity of the aerated inflation controlled anchor is 65% ~ 75% of its ultimate uplift bearing capacity by using the isochronous curve method and the transition creep method.
