Abstract：Based on wave theory，the displacement，the blasting vibration acceleration，and the stress state of slope under the same blasting vibration velocity but different vibration frequencies were studied. The results indicated that with the same blasting vibration velocity，the peak vibration displacement was in inverse proportion to the vibration frequency，while the blasting vibration acceleration was proportional to the vibration frequency；however，the maximum stress of the slope was unchanged. There was no direct relation between acceleration and stress state of the slope，and the higher the vibration frequency was，the more quickly the displacement，the acceleration and the peak stress varied along the depth of the slope. According to comprehensive consideration of mutual relationship between vibration frequency，vibration acceleration and stress state of the slope，the method of converting the acceleration in higher frequency to acceleration in lower frequency of blasting vibration was obtained. Based on the fact that the same peak stress in the slope was created by the same peak particle vibration velocity，the equivalent acceleration calculated method for limit equilibrium analysis of slope under blasting vibration was proposed，which provided theoretical basis of analyzing the slope stability under blasting vibration during slope construction.
