近几年,为避免隧道开挖过程中因复杂地质引起的各种安全事故,地质超前预报技术得到了普遍推广和应用。本文在分析传统一维、二维超前预报技术的基础上引入三维成像的概念,并进一步对自主研发的新型地质超前预报技术从理论仿真、数据处理和结果解译等方面进行阐述。最后通过实例分析和验证,三维隧道地质超前预报技术利用三维成像的优点克服了传统预报技术定位不准确的难点,而且其简易的观测系统、高效的采集流程以及通俗易懂的成果,为当前隧道地质超前探测和预报工作提供了一个准确可靠、高效简洁的新方法。
In recent years, in order to avoid various safety incidents caused by complex geology during the process of tunnel excavation, geological advance forecasting technology has been widely popularized and applied. This paper introduces the concept of 3D imaging based on the analysis of traditional one-dimensional and two-dimensional advanced forecasting techniques, and further elaborates on the new geological advanced forecasting technology independently developed from theoretical simulation, data processing and interpretation of results. Finally, by example analysis and verification, the three-dimensional tunneling geological advanced forecasting technology overcomes the difficulties of traditional forecasting technology inaccuracy by using the advantages of three-dimensional imaging. Moreover, its simple observation system, efficient acquisition process and easy-to- Geological advance detection and forecasting work provides an accurate, reliable and efficient new method.
