求翻译：目前国内的高密度电法主要应用于二维勘探，对于矿产地质勘查、工程地质勘查领域中大量的三维地质问题未能得到很好的解决。即使如此，近年来，二维高密度电法在重大场地的工程地质调查、坝基及桥墩选址、采空区及地裂缝探测等众多工程勘察领域仍然取得了明显的地质效果和显著的社会经济效益。另外，高密度电法还具有设备简单、使用方便、精确度高、对工程无破损等特点。是什么意思？

At present, the high-density electrical method is mainly used in two-dimensional exploration, geological prospecting for mineral, a lot of three-dimensional geological problems in the field of engineering geology exploration has not been a good solution. Even so, in recent years, two-dimensional hig
