摘要
在浅层地质工程勘察中,缺乏一种可控、无损、高分辨率的探测工具,一种新型震源电磁驱动式轻便高频可控震源,填补了此项空白。通过调制扫描频率,可控震源具有探测深度大、分辨率高、工作稳定、抗干扰、效率高等优点。实际应用表明,该技术对于采空区、溶洞、隧道探测等浅层工程勘察是可行的,探测效果良好,进而拓宽了可控震源的应用领域。
In engineering-geophysical applications, there is a lack of controlled, nondestructive, high-resolution mapping tools. A portable, high-frequency, electromagnetic, P-wave vibrator system capable of bridging this gap has been developed . As far as the important contribution of the seismic source is concerned, penetration and resolution can be individually controlled through easy modulation of the sweep signal generated by this electromagnetic vibrator. The tests in some projects indicate that it has advantages with high -resolution, steady operation and highly efficiency. The feasibility and applicability of this system has been tested in shallow engineering-geophysical applications, such as in mined-out area Karst and tunnel, which consequently develop the application field in survey.
