摘要

通过与实际资料的对比，可以准确预测出工作面前方30m左右范围内的地质情况。与同一隧道断面的进口探地雷达进行对比，其效果优于进口探地雷达，表明LTD-2100探地雷达是隧道施工超前地质预报的较好方法。结果表明，LTD-2100探地雷达具有扫描速度快、操作简单、重量轻、分辨率高、图像直观等优点，在超前地质预报中已显示出较强的优势。在隧道工程中具有十分广阔的应用前景。

Application of LTD-2100 ground penetrating radar to advanced forecast in diversion tunnel of Jinping Hydroelectric power Station

Taking the advanced geological forecast in diversion tunnel of Jinping Hydroelectric power Station as an example, the principle of LTD-2100 ground penetrating radar (GPR) is expounded, and it is also stated in detail how to set parameter, layout measuring line, detect, process the data, as well as explain the detection results. It can forecast accurately the geological condition within about 30m in front of the work face by comparing between the forecast achievement and the real information. It has been contrasted with the imported GPR in the same tunnel section, and its results are better than those of imported GPR It is shown that LTD-2100 GPR is a better method for the advanced geological forecast in the tunnel construction. It is shown that LTD-2100 GPR has not only fast scan, simple operation, light weight, high resolution and intuitionistic image, but also has already shown strong superiority in advanced geological forecast. It has a very broad application prospect in the tunnel project.
