摘要(Abstract)：

采用钻孔爆破和水压爆破相结合的方法拆除钢筋混凝土三孔导流涵洞。文中论述了钻孔爆破和水压爆破参数的确定、安全技术措施、起爆网络和起爆顺序 ,对作用在涵洞壁上的水中冲击波峰值压力及有关参数进行了计算。此外 ,还介绍了爆破震动监测及对监测结果的分析 ,并在分析的基础上讨论了局部涵洞壁出现裂缝的原因。
A reinforced concrete diversion culvert with three channels was demolished by a method of combining drilling and blasting with water pressure blasting. In this paper, the determination of parameters for drilling and blasting and water pressure blasting, safety precautions, priming network and sequence were expounded, and the peak pressure of in water shock wave on walls of the culvert and relative parameters calculated. In addition, the monitoring of blasting vibration and the analysis on monitoring results were introduced, and the reasons for come up of fissures on partial walls of the culvert discussed based on the analysis.
