High-density electrical method has been widely used in the field of engineering survey, and has obtained good application effect with its own characteristics, in many aspects reflects superiority comparing with the normal electrical method. The exploration example of one transformer substation shows that the High-density electrical method in overburden thickness detection has the advantages such as low cost, high efficiency, and good effect etc. It has higher application value in engineering application aspect.% 高密度电法在工程勘察领域得到了越来越广泛的应用,并以其自身的特点取得了良好的应用效果,在诸多方面体现出了较常规电法的优越性。某变电站的勘查实例表明,高密度电法在探测覆盖层厚度方面具有成本低、效率高、效果好等优点,在工程应用方面具有较高的应用价值。
