引入和比较了Singh-Mitchell和З.Г.Тер-Мартиросян两个蠕变模型,并发现当取时间t=t1时这两个模型具有完全相同的形式,由此说明了模型的正确性和广泛适用性。借助于三轴蠕变仪对清江水布垭古树包滑坡滑带土进行了不同固结压力、不同剪应力水平下的蠕变试验。试验结果不仅符合Singh-Mitchell蠕变模型,而且还得出了蠕变参数与固结压力及剪应力水平无关的结论。 The two creep models of Singh-Mitchell and З.Г.Тер-Мартиросян were introduced and compared, and the two models were found to have exactly the same form when time t = t1, which shows that the model is correct and extensive applicability. The creep test under different consolidation pressure and different shear stress level was carried out by using the triaxial creep meter. The experimental results not only accord with the Singh-Mitchell creep model, but also conclude that the creep parameters are independent of the consolidation pressure and shear stress level.
