摘要
清江隔河岩水利枢纽导流隧洞出口段为全风化页岩，洞底下为石牌页岩，且系风化层移裂隙发育，是整个隧洞开通困难最大的障碍地段，通过设计、施工人员共同努力与安全监测，工期历时11个月，于1997年12月15日完工过水，创造国内当年开工当年过水的新纪录。
The outlet of the diversion tunnel of the Geheyan project was the most difficult zone to excavate because of the completely weathered shale. with completely weathered Shipai shale underneath the tunnel. and the development of cracks. It took the designers. builders and monitoring engineers 11 months to complete the tunnel on 15 th December. 1997. and thatcreated a new record in China in completing a tunnel in one year.
