摘要
微动探测技术以其无需人工源、抗干扰能力强、便捷环保等优点,在城镇附近干扰较强、不可破坏的物探环境中优势突出。我们对微动理论及野外工作方法进行了系统的研究,自主编制了高分辨率频率-波数法处理软件,本文介绍了微动勘探技术应用的案例,通过提取频散曲线及视S波速度分层,刻画了地层的速度结构和地热异常特征,证实了微动勘探在地热资源勘查上有着较好的勘探效果,具有一定的方法优势和广泛的应用前景。
Microtremor survey technique has the advantages of needing noartificial source, having strong anti - interference, being convenient and environment-friendly, etc., and is best applied in an area near the town where the interference is strong and destruction is not allowed. We have made a systematic study of the microtremor theory and the field work method, and independently programmed for the high-resolution frequency wave number method. This paper introduces the application of microtremor survey technique, by extracting frequency dispersion curve and Swave velocity layering, depicts the velocity structure and geothermal anomaly characteristics of the stratigraphy, and confirms that it has good effect in geothermal resource exploration and has certain advantages and broad application prospect.
