The developing of dangerous rock is due to release of in-situstressinrock, aeolation, water erosion and root flerry.
地应力卸荷、风化、流水侵蚀、植物根劈是危岩发育的主要原因。

Due to high insitustressin the powerhouse area, important deformation of local surrounding rock, rock burst, shotcrete spalling occur during excavation.
由于场区地应力比较高,在开挖期间出现了局部围岩的大变形及岩爆、喷混凝土层剥落等不良现象。
