摘要
介绍了古城水电站调压井在不良地质条件下的主要开挖施工方案:超前固结灌浆、溜渣井施工、大井扩挖与支护、大井扩挖过程中的监测,对类似地质条件的竖井和斜井开挖有一定的借鉴作用。
Main construction scheme for surge shaft excavation under poor geological conditions at Gucheng hydropower station is described in this paper,including advanced consolidation grouting,mucking shaft construction,big shaft enlargement and support,monitoring during enlarging.These methods are used for reference for vertical and inclined shaft excavation under similar geological conditions in the future.
