十三陵电站高压管道斜井开挖及塌方处理

Inclined Shaft Excavation and Collapse Treatment of Penstocks for the Ming Tombs Pumped Storage Hydroplant

十三陵电站高压管道，由于围岩地质条件复杂，采用了多种施工方法进行了斜井、导井施工，在扩挖时严格遵守了“新奥法”施工原则，战胜了四次大塌方，使斜井顺利穿越蟒山山体。

Several construction methods were used to excavate the pilot shaft of the inclined shaft for penstocks of the Ming Tombs Pumped Storage Hydroplant for complicated geological conditions of the adjoining rocks.The construction principles of NATM were strictly followed as conduits enlarged, and 4 collapses were overcome,making the inclined Shafts drive through Mang shan mountain.
