中文摘要：

通过分析隧道超前地质预报发展历程和常见隧道超前地质预报方法适用性,提出以地质调查法为基础,与物探法、 超前钻探法相结合的隧道综合超前地质预报方法,并建立合理的预报工作流程.将 Google Earth软件运用到隧道超前地质预 报之中.以大坪山隧道为工程背景,运用综合超前地质预报技术对掌子面前方一定范围内不良地质条件进行预测预报,验证 了隧道综合超前地质预报方法在实践中的可行性和准确性,为今后类似隧道超前地质预报提供了一种思路.

英文摘要：

By analyzing the history of tunnel advanced geological prediction development and the characteristic of usual tunnel advanced geological prediction methods, a comprehensive advanced geological prediction method was put forward, which was based on geological survey, and combined with physical exploration method and advance drilling method. The reasonable process for forecast work was also established. The Google Earth software was applied into tunnel advance geological prediction. Taking DA-Pingshan tunnel as an example, the poor geological conditions in front of DA-Pingshan tunnel face was successfully predicted by the comprehensive advance geological prediction method. This verify that the comprehensive advanced geological prediction method is accurate and feasible in practice. And it also provides a train of thought for the similar tunnel advance geological prediction in future.
