摘　　要：在京秦高速公路青龙连接线 9号标段的路堑开挖中 ,进行了爆破震动监测。根据测得的数据 ,并利用速度判别法、加速度判别法、动应力分析法和等效静荷载法 ,综合评价了爆破震动对岩石边坡稳定性的影响。评价结果表明 ,工程中采用的爆破方法是合理的 。Monitoring of blasting vibration was carried out in cut excavation in section No 9 of Qinglong linkage line of Beijing to Qinhuangdao expressway According to measured data and by use of the velocity and acceleration criteria,the dynamical stress analysis and equivalent static load method,the influence of blasting vibration on stability of rock slope was comprehensively evaluated The evaluation result shows that the blasting method used in the project is reasonable and harmless to the slope of this section
