| 摘 要： | 不良地质条件下,开挖支护采用一般的支护如超前锚杆、系统锚杆、挂网喷混凝土等方法已经无法满足施工要求,必须采用更强的支护方法。在糯扎渡水电站排水洞工程中采用挂网喷混凝土结合钢支撑支护或挂网喷混凝土结合钢支撑及管棚法支护,取得了良好的效果。

| Abstract: | Under unfavorable geological conditions,the regular supporting system such as advanced anchorage bolts,systematic anchorage bolts,wire mesh and grouting and etc.,can no longer meet the construction requirement.So a more adequate supporting system is called for.In the excavation of the discharge tunnel of the Nuozhadu hydroelectric project,the wire mesh shotcreting was used in corporation with the steel supporting or wire mesh grouting with steel supporting and pipe-shield supporting system.The result was satisfactory. |
