| 摘 要： | 针对传统动态应力比评价标准仅评价地下结构物可见损伤的不足，将爆破震动扰动下引起岩体内纵波波速变化这一因素考虑进去，从而把动态应力比评价标准扩充到了对岩体内部不可见损伤的评价，补充了原有标准的不足，从而为进一步加强地下结构顶板稳定性管理提供了相当有用的依据。

| Abstract: | In consideration of the change of speed of P wave induced by the interferences of blasting vibration, this paper enlarges the dynamic stress ratio evaluation criteria to the sightless damage in rock-mass, so as to overcome the shortages of the conventional evaluation criteria that only can be used to assess the eyeable damage in underground structure under the invariable speed of P wave. It gives a very useful basis for further strengthening the stability control of underground structure's roof. |
