摘要
在浅层地质工程应用中,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,填补了空白。通过简单调制扫描频率,可控震源具有探测深度大、分辨率高、工作稳定、抗干扰、效率高等一系列优点。实际应用表明,该技术对应用于采空区、溶洞探测等浅层工程勘察是可行的,探测效果良好。这拓宽了可控震源的应用领域。
A portable, high-frequency, electromagnetic, P-wave vibrator system was developed. Penetration and resolution can be individually controlled by easy modulation of the sweep signal generated by this electromagnetic vibrator. The tests in some projects indicate that this system has the advantage of high-resolution, steady operation and high efficiency. The feasibility of this system has been tested in shallow engineering-geophysical applications, such as in mined-out area and karst. This will develop the application field in survey.
