【摘要】：近年来,TSP(Tunnel Seismic Prediction)隧道地震预报法已经普遍运用于隧道建设中,在预防隧道开挖时发生地质灾害方面发挥了显著作用,已有不少成功案例,但也存在一些漏报和错报。文章从分析TSP法地质预报存在的缺陷及在数据采集过程中可能遇到的各种干扰入手,总结和补充了如何避免或降低各种干扰可采取的应对措施,并通过不断对比预报情况与实际围岩开挖情况,进行数据反分析,积累了一定的数据处理参数设置经验。同时,通过不断分析、总结TSP法对如破碎带、富水区等不良地质体所表现出的不同特性,提出了资料解译时的快速分析方法,并运用到实际预报工作中,取得了较好的效果。
[Abstract]:In recent years, the earthquake prediction method of TSP Tunnel Seismic prediction has been widely used in tunnel construction, and has played a significant role in preventing geological hazards during tunnel excavation. There have been many successful cases, but there are also some false reports. Based on the analysis of the defects of TSP geological prediction and the possible interference encountered in the process of data acquisition, this paper summarizes and supplements the countermeasures that can be taken to avoid or reduce the various kinds of interference. By comparing the forecast situation with the actual surrounding rock excavation situation, the data back analysis is carried out, and the experience of setting the data processing parameters is accumulated. At the same time, through continuous analysis, this paper summarizes the different characteristics of TSP method for bad geological bodies such as broken zones and water-rich areas, and puts forward a fast analytical method for interpretation of data, which has been applied to the actual prediction work and has achieved good results.
