针对隧道施工期洞身段的滑坡超前地质预报，以某高速公路某座隧道为例进行技术探讨，介绍了隧道工程概况及滑坡区域基本工程地质条件。采用地质法中的趋势外推法、地质雷达波反射法、超前钻孔法，对滑坡在隧道穿越区的延伸、规模、物质组成、工程和物理力学特性及其与隧道的空间位置关系进行了分析预测。得出了超前地质预报的综合评判结论，减小甚至规避了单一方法的缺陷，并提出了针对性的施工处治思路。实践证明本隧道洞身段滑坡超前地质预报是成功的，对类似工程具有一定的参考价值。

This paper examines advanced geological forecasting of landslide about one tunnel body duringconstruction.It takes an expressway tunnel as an example for technology and evaluation.It introduces the generalsituation of the tunnel engineering and the basic engineering geological condition of the landslide.Several methodsincluding trend extrapolation of geology,reflection wave of geological radar,and advanced borehole are adopted foranalytical prediction about the features of landslide.These features include the extension, scale, materialcomposition,engineering and physical and mechanical properties,and the spatial locationrelation with the tunnel.A comprehensive conclusion is obtained about advanced geological forecasting.It can reduce and /or even avoid thedefects of the single method,and put forward the corresponding construction treatment ideas.
