瞬变电磁法在某水电站断层勘查中的应用研究
|
摘要
断层是影响水电站稳定的重要因素之一,某水电站由于现场条件的限制,应用其他的物探方法难以达到勘探深度,且成本较高,瞬变电磁法具有高效、低成本、高分辨率的技术特点,能够克服现场条件。通过本次工作,查明了某水电站断层的具体位置及深度,为水电站的后期处理提供重要依据。
Fault is one of the important factors that affect the stability of hydropower station.Due to the limitation of site conditions,some hydropower stations are difficult to reach the exploration depth by using other geophysical methods,and the cost is high. The transient electromagnetic method has the technical characteristics of high efficiency,low cost and high resolution, and can overcome the scene conditions.Through this work, the specific location and depth of faults in a hydropower station have been identified,which provides an important basis for the post-treatment of hydropower stations.
