High stress rock burst and water outburst occurred in Erlangshan and Huayingshan road tunnels separately.
对二郎山和华蓥山隧道在建设过程中的高地应力岩爆与岩溶涌突水问题进行了研究。
Due to high in situ stress in 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。
The prevention and control of rock burst are of great significance for safely exploiting deep deposit in high-stress area.
岩爆的预防和控制对深部高应力区矿床的安全开采具有十分重要的意义。
Rock burst is often met in excavation unloading of underground engineering in high geo-stress areas.
岩爆是高地应力区地下工程开挖卸荷产生的动力现象。
So steel fiber reinforced shotcrete should be the first choice for tunnel support on the condition of tunnel crossing high ground stress and having rock-burst tendency.
因而认为钢纤维混凝土应成为高地应力条件下的有岩爆倾向的隧道支护首选。
