| 摘 要： | 爆破振动危害动态应力比评价方法(DSR)是根据爆破振动实地监测及质点振速预测方程，结合现场损伤破坏调查而求得岩土结构爆破振动破坏判据的一种新方法。该法综合爆破振动水平、岩体特征性质、现场条件及岩土支护系统等因素，可以较全面地反映岩土结构受爆破振动时的动态应力状态和损伤破坏程度。通过几个露天矿采场边坡的动态应力比评价，说明了该方法的内容与应用过程，揭示了其本质与优点。

| Abstract: | Blasting vibration dynamic stress ratio evaluating method (DSR), a new method combining the ground survey to obtain geotechnical structure blasting vibration failure criterion, is based on the result of blasting vibration ground monitoring and particle vibration velocity forecasting equation. Considering the factors of blasling vibration level, rock characteristic, ground condition and rock support system, this method can more extensively refelect the dynamic stress state and damage degree. The evaluation of some open pit slopes' explains the content and application progress of this method, and delineates its essence and advantage. |
