摘要
研究目的:通过隧道地质超前预报,掌握掌子面前方地质信息,为施工单位优化施工方案、安全科学施工、提高施工效率、缩短施工周期等提供依据,为预防隧道塌方、突水、突泥、突气等可能形成的灾害性等事故及时提供信息,具有重大的社会效益和经济效益。研究方法:本文以作者在八盘岭隧道和长梁山隧道地质超前预报的亲身经历为背景,着重介绍了隧道地质超前预报在我国铁路、公路、城市轨道交通等工程的长大隧道施工中的重要作用和研究的重大意义。研究结果:本文系统地分析和归纳总结了隧道地质超前预报的前期准备工作、地质超前预报目的及内容、预报的各种方法、预报成果的输出形式和方式、预报时间安排和过程、探讨和研究的结论等,侧重介绍了地质超前预报的各种方法。研究结论:地质超前预报是隧道施工的一个重要环节,应纳入施工工序,可以指导施工,为隧道施工提供科学依据。
Research purposes：Based on the geological forecast on tunneling, the geological information of heading face of the tunnel is obtained. Therefore, the forecast provide important foundation for optimizing construction method, raising the construction efficiency and shortening period. And the forecast also provide message for preventing tunnel collapses, gushing water, mud and gas, so it has the important social and economic performances. Research methods：With the background of work experience of the author himself on Bapanling and Changliangshan Tunnel, the important role and significance of geological forecast on construction of long - large tunnel in railway, highway and urban rail transportation in China are emphasized in this paper. Research results： The planning, objectives, contents, methods, outcome＇s form, schedule and the conclusion of the forecast are also summarized in this paper. And it pay more attention to introduce the methods of the forecast.
Research conclusions：Geological forecasting is an important link to tunnel construction. It should be brought into construction procedure so as t instruct tunneling and offer the scientific basis of tunnel construction.
