【摘要】：随着国家大规模基础建设,隧道工程在各个线路工程中的比重也越来也大;由于隧道受长度、埋深、不良地质等因素的影响,施工过程中会遇到很多问题,例如突水、突泥、塌方、岩溶等。类似的不可预料的地质灾害已经成为困扰工程施工的主要难题。为了保证隧道安全顺利施工,保证施工人员、财产安全,超前地质预报在工程中应用得越来越多,越来越受施工单位重视。TRT-6000系统是我国2006年引进的一种新的超前地质预报系统。由于TRT技术引进晚,国内使用量少,积累的经验少,针对TRT技术应用的提高数据准确性及可靠性的研究更少,操作人员技术水平较低,在很大程度上影响了本技术的推广应用。比较严重的情况是,在使用TRT-6000系统时,由于应用操作不当,后期处理与解释不正确,可能出现误判,对工程施工与安全造成严重的影响。本文依托TRT-6000超前预报系统在山西中南部铁路通道多个隧道工程中的应用情况,着重研究了TRT-6000系统的工作原理、操作要点、数据处理方法,并成功应用于多个隧道工程(标段)的超前地质预报;获得了大量的实测数据和图像,积累了大量的应用经验,进而提出了判定、预报隧道工程中不良地质现象(包括溶洞、断层、突水、突泥等)的准则;总结分析了TRT-6000系统自身存在的问题,提出并实现了系统操作、数据处理过程中的改进优化措施,使得该系统的地质预报工作更加方便、简单、快捷,成本更低,进一步提高了系统预报的准确性,为隧道工程安全、快速、经济施工提供了可靠的技术保障。
[Abstract]:With the large-scale infrastructure construction in the country, the proportion of tunnel projects in various line projects is also increasing. Because the tunnel is affected by factors such as length, depth of burial, bad geology, and so on, many problems will be encountered in the construction process, such as water inrush and mud outburst. Collapse, karst, etc. Similar unpredictable geological disasters have become a major problem in engineering construction. In order to ensure the safe and smooth construction of tunnel, ensure the safety of construction personnel, property and advance geological forecast in engineering, more and more attention has been paid by construction units to the. TRT-6000 system is a new geological forecast system introduced in 2006 in our country. Due to the late introduction of TRT technology, less domestic usage, less accumulated experience, less research on how to improve the accuracy and reliability of data in the application of TRT technology, and a low level of technical level of operators, the popularization and application of this technology is affected to a great extent. The more serious situation is that in the use of TRT-6000 system, due to improper application and operation, the late processing and interpretation is incorrect, which may lead to misjudgment, which will have a serious impact on the construction and safety of the project. In this paper, based on the application of TRT-6000 advanced forecast system in many tunnel projects of railway passage in central and southern Shanxi Province, the working principle, operation key points and data processing method of TRT-6000 system are studied emphatically. It has been successfully applied to the advanced geological prediction of many tunnel projects (segments), obtained a large number of measured data and images, accumulated a great deal of application experience, and put forward the judgment to predict the bad geological phenomena (including karst caves) in tunnel engineering. The principles of fault, water inrush, mud outburst, etc., summarized and analyzed the problems existing in the TRT-6000 system, put forward and realized the improvement and optimization measures in the operation of the system and in the process of data processing, which made the geological prediction work of the system more convenient and simple. It is fast and low cost, which further improves the accuracy of system forecast, and provides reliable technical guarantee for tunnel engineering safety, fast and economical construction.
