中文摘要：

地质分析法作为超前预报的根基，对其研究程度直接影响隧道综合超前预报的准确性，尤其是地质环境条件复杂的隧道。为此，提出了基于断裂带山岭隧道的现代地质分析方法：即以山岭隧道所穿越的地质体为研究对象，运用系统性理论，以“体-面-线-点”（三维地质体；区域平面；隧道沿线、不良地质体与隧道的交线；洞内各桩号段）为预报分析为重点、以“点-线-面-体”为检查预报失误原因的辅助循环研究体系，获得断裂带山岭隧道穿越的地质预报剖面图和断面图。通过与实际开挖揭露的地质条件对比，分析影响预报精度的因素，进而总结、归纳为提高后续预报的准确性提供依据。引入在建的大坪山隧道为例进行了应用分析，取得了较好的预报效果。

英文摘要：

As the foundation of advanced prediction, the research of geological analysis method directly influences the accuracy of tunnel comprehensive advanced prediction, especially the tunnels under complex geological environmental conditions. For this reason, a modem geological analysis method based on fault zone mountain tunnel is proposed： taking the mountains tunnel through geological body as the research object, using systematic theory, taking the body-surface-line-point （＂body＂ for 3D geologic body; ＂surface＂ for regional plane; ＂line＂ for along the tunnel, intersection line of adverse geologic body and tunnel; ＂point＂ for pile section in tunnel） as the focal point of the forecast analysis, with ＂point-line-surface-body＂ for the auxiliary cycle research system of inspection forecast error reason, gain the geological forecast profile and cross sectional drawings of mountain tunnel passing through fault zone are obtained. Compared with the geological conditions of actual excavation revealed, the influencing factors of the forecast accuracy are analyzed and summed up to provide a basis for improving the accuracy of the subsequent forecast. The good forecast effect is obtained in the analysis example of Daping mountain tunnel.
