从荷载水平的角度出发,利用改进的非等间距灰色预测模型对土工合成材料的蠕变特性进行了预测。即利用高荷载水平下的蠕变变形预测了低荷载水平下的蠕变变形,同时利用高荷载水平下的蠕变断裂时间预测了低荷载水平下的蠕变断裂时间。实例预测计算的结果与试验结果比较吻合,高荷载水平下的蠕变试验可预测低荷载水平下的蠕变特性,并可节省了时间。 From the perspective of load level, the creep characteristics of geosynthetics are predicted by the improved non-equidistant gray prediction model. That is, creep deformation at high load level was used to predict creep deformation under low load level. At the same time, creep rupture time at high load level was used to predict creep rupture time at low load level. The results of the example prediction calculation are in good agreement with the experimental results. Creep tests at high load levels can predict creep characteristics at low load levels and save time.
