土体流变破坏时间的灰色预测模型

Grey forecasting model for the failure time in the course of soil creeping

根据不同载荷条件下土体蠕变破坏的时间数据列,建立了土体流变破坏时间的灰色预测模型。该模型能根据土体在较高应力条件下的蠕变破坏时间预测其在较低应力水平条件下的蠕变破坏时间,可用于边坡破坏预测、岩土工程、岩土力学试验等领域。

According to the sequence of the soil creeping failure time under different loading conditions, a grey forecasting model for the failure time in the course of soil creeping is established. By using the failure time in the condition of heavy-loading, the model can forecasting soil failure time in creeping test in the condition of light-loading, so it can be used in the field of slope failure forecasting, creeping, material mechanical test and so on.
