| 摘 要： | 研究了基于单炮小药量震源激发地震波场,24个三分量检波器拾取反射波的单炮多道隧道反射波超前预报数据采集排列。现场试验表明,其预报精度与同样基于地震反射波原理的TSP方法一致,但由于数据采集仅需一次放炮激发,且炮点位置可在边墙上,也可在掌子面上,极大地降低了数据采集的时间和风险,提高了现场施测的灵活性

| Abstract: | In this paper,an acquisition array of seismic reflections data with single shot and multiple tracks acquired by 24 three-component detectors based on small quantity of explosion source to excite seismic wave field is presented for tunnel advanced geological prediction.The site test shows that the precision of the new array is at the same level as that of the commercial TSP(Tunnel Seismic Prediction) method based on seismic reflections.Since the acquisition with the former only need one shot being able locat... |
