中文摘要：

在成功预报宜万铁路云雾山隧道大型含水溶腔的工程实践中,发现了地下大型含水体对地震波的特殊反射现象,用地震波在双相介质中的传播理论解释了这种特殊的反射现象,分析了地震波在岩石与水体界面的反射、透射规律.提出了地震波法预报中对大型地下含水体的判识准则,并于青岛胶州湾海底隧道进行了两次现场正演试验,由海底基岩对海底界面进行了探测,试验结论很好地验证了该判识准则的正确性.研究结论对于有效预报地下含水体,特别是在预防矿井、隧道等地下工程大型突水事故方面具有重要的应用和推广价值. 关键词：地震波法;反射规律;超前预报;现场试验 分类号：P631 Field-testing study on seismic reflection response of large-scale underground water-bearing body ZHANG Xiao LI Shu-Cai ZHANG Qing-Song XUE Yi-Guo LIU Ren-Tai SUN Ke-Guo ZHANG Bo ZHAO Yan

英文摘要：

A special reflection phenomenon of seismic waves from the large-scale underground water-bearing body has been discovered in a seismic method advanced prediction in Yunwu tunnel. According to the classical theory of seismic wave reflection and transmission, this phenomenon has been explained. In order to verify the correctness and applicability of the conclusions, two field tests have been carried out in Qingdao Jiao Zhou sub sea tunnel. TSP method was used to detect the seafloor in the field tests of sub sea tunnel, and the results verify the special laws of seismic wave reflection. According to the field tests conclusions and engineering examples, seismic wave reflection laws of large-scale underground water-bearing body have been summarized. In engineering practice, especially for advanced geology prediction the laws have important application value.
