| 摘 要： | 掌鸠河引水供水工程厂口隧洞位于输水线路后段,隧洞斜穿普渡河断裂带,岩体破碎、质软,隧洞围岩稳定性很差,为此,采用了特殊的、有针对性的结构措施和施工方法。过普渡河断裂带洞段在实施超前地质预报、超强一次支护、及时跟进二次衬砌、短循环进尺等具体工程措施保障下顺利贯通。

| Abstract: | The intake tunnel of the Zhangjiuhe Water Transfer project,located at the lower section of the water transfer alignment,runs diagonally through the Puduhe faulted zone where the rocks are weak and highly fractured resulting in poor stability.So some special and unusual engineering methods and structures were adopted accordingly.The tunnel section at the Puduhe fault zone was successfully completed with the application of engineering measures including the forecasting of geological conditions,super-intensive primary support,timely secondary lining and close-cycle advance. |
