The technique reveals the distribution of active faults clearly.


成都市地下空间勘察中的频率谐振勘探成像结果的一段(1,波阻抗比率剖面)。在此也进行了浅层反射地震方法勘查(2,已经转换到深度剖面)。

Exploration of shallow reflective seismic methods are also been applied in this area(P2).

对比表明,二者对地质结构的表述一致,但频率谐振对断层破碎带边界和内幕的岩石密度变化显示了更高的分辨能力。

The statements of geological structure are consistent,But SFRT shows higher resolution for changes in rock density at fault fracture zone boundaries and insiders.
