地质法在隧道超前地质预报中的作用探讨

Role of Geological Method in Tunnel Advance Geological Prediction

当前隧道超前地质实际预报中只注重物探仪器的应用,忽略地质方法的作用,从而导致预报精度不高,坚持以地质法为基础、以物探为手段的综合超前预报可以大大提高预报精度。文章首先介绍了超前地质预报的任务和地质法的内容;然后研究了物探法的缺陷,并对地质法在超前预报中的作用进行了分析;最后,确定地质法对物探法的指导作用,是超前预报的基础和核心,是提高超前地质预报水平的重要保证。

So much attention has been paid to geophysical equipment in present practice of tunnel advance geological prediction while the role of geological method was neglected that contributed to low forecast accuracy. Persisting in comprehensive advance prediction with geological method as the basis and with geophysical method as the means can enhance forecast accuracy greatly. Firstly, the task of advance geological prediction and the contents of geological method were introduced. Then the shortcomings of geophysical method and the role played by geological method in advance geological prediction were analyzed. Finally, the guidance of geological method to geophysical method was confirmed, geological method is the basis and core in advance geological prediction and an important guarantee for enhancing the level of advance geological prediction.
