锦屏二级水电站深埋长隧洞群具有工程规模巨大、高地应力、地形地质条件复杂等特点,在历时9a的开挖施工过程中遇到极强岩爆超过千次。在介绍该电站隧洞群几次典型极强岩爆特征的基础上,总结了一套包括组织机构设立、预报监测措施选取、施工机械设备选配、爆破方案动态调整、支护材料和支护参数选择、爆后针对性治理的极强岩爆综合防治体系,该体系确保了工程的有效推进,实现了该电站7条隧洞的全部贯通。
錦屏二級水電站深埋長隧洞群具有工程規模巨大、高地應力、地形地質條件複雜等特點,在歷時9a的開挖施工過程中遇到極彊巖爆超過韆次。在介紹該電站隧洞群幾次典型極彊巖爆特徵的基礎上,總結瞭一套包括組織機構設立、預報鑑測措施選取、施工機械設備選配、爆破方案動態調整、支護材料和支護參數選擇、爆後針對性治理的極彊巖爆綜閤防治體繫,該體繫確保瞭工程的有效推進,實現瞭該電站7條隧洞的全部貫通。
