摘 要:为保证深埋特长隧道的施工安全,在施工阶段必须根据隧道的地质情况,建立一套适合于该隧道地质情况的超前预报体系。依托锦屏水电站辅助洞超前地质预报工作,通过不断总结、研究、对比,建立了一套适合于深埋特长隧道的超前预报体系,即以地质分析为主线,物探方法为手段,多种方法相互印证和补充,宏观预报、中长距离预报、短距离预报、特殊方法相结合的综合地质预报体系,取得了较好的应用效果。An advance forecast system which is suitable for the geological conditions during construction period should be established according to it for the sake of construction safety of deep and excessive long tunnels. By continuously summarizing .studying and comparing, the author establishes an advance forecast system which are suitable for deep and excessive long tunnels on the basis of work carried out in the auxiliary tunnels of Jinping Hydropower Station, namely a comprehensive geological forecast system with the characters of geological analysis as main line, geophysical exploration as a method, various ways confirm and complement mutually, combination of macro,middle and long distance,short distance forecast and special methods, experience show that better applied effect is achieved.
