| 摘 要： | 文章是地球物理探测湿陷性黄土暗穴的系列试验成果,大量模拟计算和野外试验表明,电磁波和弹性波的两大类地球物理探测技术,是探测黄土暗穴的主流技术。而高密度电法和瞬变电磁法,则是成本低、效率高、准确率大的有效普查方法;多道瞬态面波技术、浅层地震勘探的组合技术,是实现黄土暗穴精细探测切实可行的实用技术;探地雷达在特定条件下才具备较高的精度。

| Abstract: | This paper presents integrated trial studies on geophysical exploration for water-eroded hidden loess cavities.Theoretical mod-eling and systematical field tests show that the electromagnetic and elastic geophysical methods are key technologies for detecting the hidden loess cavities.Being of low cost and high efficiency,the TEM and high density electrical methods,can be charged with the effective reconnaissance.Combining multi-trace surface wave analysis with shallow seismic,we may image the cavities rather exactly.While GPR could achieve satisfactory and precise result only under special surroundings. |
