需要注意的是，蠕变只是岩石随时间变化特性的一个方面。在图1中，关于完整的应力-应变曲线示出了三种情况：蠕变，即当应力保持恒定时应变增加;应力松弛，即当应变保持恒定时应力减小;当岩石沿沿着选定的卸荷路径卸荷时，这对于所施加的载荷或应力保持恒定的情况尤其相关。
It is important to note that creep is only one aspect of the time-dependent behavior of rocks. In Fig. 1, three cases are illustrated with respect to the complete stress–strain curve: creep, ie, increasing strain when the stress is held constant; stress relaxation, ie, decreasing stress when the strain is held constant; and a combination of both, when the rock unloads along a chosen unloading path. This ISRM suggested method deals only with the case of creep, which is particularly relevant for cases where the applied load or stress is kept constant.
