| 摘 要： | 利用物探方法准确高效地探测输电线路下方采空区的位置和范围对电网安全、稳定地运行具有十分重要的意义。根据采空区的地球物理性质，常使用电阻率法、电磁法、地震法等对其进行探测，但是，由于工区的干扰以及物探资料解释的多解性，单一的探测方法常常难以取得理想的效果。本文综合利用电测深法和浅层地震反射方法对高压架空线路下方采空区进行探测，研究表明电阻率法和地震法互相验证和补充，有效减少单一物探方法解释时的多解性，提高探测的分辨率和解释成果的可靠程度，为圈定采空区提供有效的依据。

| Abstract: | It is very important for the safe and stable operation of power grid to detect the location and scope of mined-out area under transmission line accurately and efficiently by comprehensive geophysical method. According to the geophysical properties of goaf, resistivity method, electromagnetic method and seismic method are often used to detect goaf, but due to the actual interference and geophysical multi-solution, a single geophysical exploration method is often difficult to achieve ideal results. In this paper, the symmetrical quadrupole section resistivity method and shallow seismic reflection method are used to detect the mined-out area under the high-voltage overhead line. The study shows that the resistivity method and seismic method are mutually validated and complementary, which effectively reduces the multi-resolution of single geophysical method interpretation, and improves the detection resolution and the reliability of interpretation results. It provides an effective basis for delineating goaf. |
