摘要
岩溶山区隧道施工过程中,大型充水溶洞是造成隧道突水突泥事故的重要因素。该文以现场试验为基础,研究了雷达探测技术在岩溶洞穴探测中的应用,分析了典型溶洞的雷达图像特征,论述了雷达探测的频率选择、探测方法、影响因素与控制方法等相关问题,提出了雷达在隧道中探测岩溶洞穴的技术流程。
In the course of tunnel construction in karst mountain area, huge karst cave with water is the important factor for karst water and mud inrush disaster. In this paper, on the base of experimentation in suit GPR technique is studied in detecting karst cave in tunnel. Typical image character of karst cave is analyzed. At the same time, frequency selection, detecting method, effect and control factors are all studied. An detecting project and technique scheme are concluded.
