摘要
针对多道瞬态面波勘探在频率-波数域提取频散曲线会出现多解性这一现象进行了研究,并利用3种不同的激震方式在多处进行了对比试验,给出了不同激震方式在频率-波数域提取频散曲线唯一性的深度范围,认为频散曲线的唯一性是进行正确地质解释的依据。
The drawing of the dispersion curve in the frequency-wave number domain often yields different results. This paper studied this problem in multi-channel transient surface wave exploration, carried out the contrast experiment by using three different seismic sources, and produced different dispersion curves, which have different unique depth ranges. It is thus held that the dispersion curve uniqueness makes up the basis of the correct geological interpretation.
