| 摘 要： | 清江隔河岩电站导流隧洞施工具有开挖断面大、地质条件复杂，工期紧的特点，于１９８７年１月１５日开工，同年１２月１５日完工通水，总工期仅１１个月，创造了国内大型导流隧洞快速施工的新水平。在洞内最大过水流速转１８ｍ／ｓ的条件下，通过采取措施，成功地将灰岩段顶拱钢筋混凝土衬砌改用锚、喷衬护，经过水考虑、锚、喷衬护未发生任何损坏。

| Abstract: | The diversion tunnel of Geheyan Project is featured by large excavated section and complicated geologic conditions. It began to be constructed on January 15, 1987, and was completed and put in use on December 15, 1987, creating new level of quickly constructing large diversion tunnel in China. The maximum velocity of water flow passing through the tunnel is up to 18 m/s. The crown of tunnel section located in limestone stratum is lined with anchorage bar and shotcrete instead of reinforced concrete, and any damage was not discovered on the liner during diversion period. |
