摘要
此研究提出一种准确、快捷且方便的方法以研究隐伏地裂缝的分布及其随深度变化的特征。通过分析发现隐伏地裂缝的发育状况符合绕射波的基本原理,利用理论公式推算出绕射波的时距曲线方程,使用正演法分析绕射波的形态及其特性。最后使用实际的单炮记录等地质资料应用该方法识别隐伏地裂缝的位置及发育状况。
This study presents an accurate, fast and convenient method to study the distribution of underground fissures and their features change with depth. Through the analysis we found the development of underground fissures is in line with the basic principles of wave diffraction. Theoretical formulas are used to calculate time-to-distance curve equation. Forward calculation is used to analyze the morphology and properties of diffracted waves. Finally, this method is used to identify the location and development conditions of certain underground fissures.
