尾矿坝浸润线的雷达探测技术

浸润线是影响尾矿坝安全稳定性的一个重要因素,因此有必要对其位置和分布进行探测。探地雷达作为一种物探设备与手段已经在水坝浸润线的探测工作中得到应用,本文将雷达探测技术引入到尾矿坝浸润线的探测中,从雷达探测机理、雷达正演分析和尾矿坝浸润线的物理特征上论证了该方法的适用性和可行性。文中解释了使用雷达探测浸润线的具体方法与过程,从正演和反演两方面分析了浸润线雷达探测图像的特点。在方法实证中对一具体的尾矿坝浸润线进行了探测,发现探测结果与钻孔检测的浸润线数据基本符合,这充分说明了雷达探测技术在尾矿坝浸润线探测工作中是适用和可靠的。

Tailings dam saturation-line detection of radar technology

The saturation line is an important factor to affect the stability and safety of the tailings dam,it is necessary to detect its location and distribution.As geophysical equipment and tools,ground penetrating radar(GPR) has been applied in the dam detection of saturation line.The paper introduced radar technology into the tailings dam saturation line detection,demonstrated the applicability and feasibility of the technology from radar detection mechanism,radar forward analysis and physical characteristics of the tailings dam saturation line.The article explains the methods and processes for the use of GPR to detect saturation line,and analysis the characteristics of the saturation line radar images from the forward modeling and inversion analysis.The author applied GPR on a specific tailings dam to detect saturation line,and the detection conclusion basically in the same with the drilling detection data.It fully shows that the GPR technology is applicable and reliable in the detection of the tailings dam saturation line.
