振动主频对质点振速测量影响的试验研究

振动主频是评价爆破地震振动危害的重要参量，该参量主要通过对边坡，坝堤，地下结构、建筑物等设施物自振频率的响应来影响质点振速的监测。本试验模拟临近边坡的深孔爆破，采用ＣＤ－１型速度传感器研究了振动主频对质点振速测量的影响规律，给出了在试验条件下的经验公式，并说明了现场实践中的应用原则。

Experimental Research on Influence of Main Frequency of Vibration on Measurement of Vibration Rate of Particle

The main frequency of vibration is an important parameter for evaluating the harm of the vibration of blast seism,which will inflence the monitoring to the vibration rate of particle mainly by the response of self-vibration frequency of such facilities as slope,dam,underground structures and buildings.This paper introduced that long hole blasting near slope was simulated and the influence of the main frequency of vibration on the measurement of the vibration rate of particle was studied with CD-1 velosity transducer,presented empirical formula on experimental condition and explained the application principle in practice on site.
