The deformation of the structure changes very fast as the loads change with time. The effect of the inertia force can't be ignored.

由于外加的载荷随时间变化得很快，结构的变形也变化得很快，惯性力的作用将不可忽略。

The forecasting results illuminated that the chief effect to deformation is the total load and the following is effect time, so the test rock has evident rheological characteristic.

结果表明该岩石的变形最主要的影响因素是总荷载，其次是持续时间，这表明该岩石具有明显的流变效应。

The damage effect of pulling anchor was discussed, and the concepts of the deformation damage effect and the time damage effect were developed.

另外，就锚杆拉拔损伤效应问题进行了讨论，引入了变形损伤效应和时间损伤效应的概念。
