常见隧道不良地质洞段的预测及塌方的处理

Prediction of Tunnel Section with Common Poor Geological Conditions and Collapse Treatment

我国水电建设正处于大发展时期,大型的地下厂房、地下洞库群、长距离的引水隧洞将不断增加,且规模大、地质情况复杂、难度大等,根据不同的地质条件和开挖尺寸,可以选择不同的施工方法并取得不同的施工效果。对软弱围岩和断层的预报、预测、防止和处理方法进行了论述。

In China,construction of hydropower projects is in rapid development stage,so large-sized underground powerhouses,underground cavern complex,long distance headrace tunnels are increasing,resulting in large scale structures,difficult geological conditions and great challenges.Different construction results are gained with different construction methods according to different geological conditions and excavation sizes.In this paper,prediction,prevention and treatment for weak surrounding rocks and poor geological faults are discussed.
