The bigger the specimen size is, the more notable the sensitivity of rock dynamic strength dependence to strain rate is, and the smaller discreteness of the obtained rock dynamic strength is.

试件尺寸越大，岩石动态强度对应变率依赖的灵敏性越显著，所测得的岩石动态强度离散性越小；

As for the size of fractured rock, it is related with the dynamic strength which rock mass can reach.

表现在破坏块体的尺寸上，最小的破坏尺寸与所能达到的强度有直接的关系。

Because of weak strength of soft interlayers, it is noted that rock dynamic stability caused by soft interlayers should be calculated and analyzed.

软弱夹层是岩体中的薄弱部位，其动力响应问题是岩体工程稳定性分析中的一个重要问题。
