子波方法在云南人工地震测深资料处理中的应用

Application of subwave method to processing the data of seismic sounding in Yunnan Province

应用地震子波方法对云南人工地震测深资料进行了分析计算。结果反射波与折射波的处理存在明显差异。反射波较折射波对地层横向和纵向上的变化反应更为敏感。影响子波宽度的因素并非单一,特别是在云南这样地质结构极其复杂的地区。正是考虑到这些因素,仅选用了云南丰富的人工地震资料中的部分记录质量较好的数据进行计算。结果与常规方法的解释基本吻合。该方法虽不能对界面结构进行精确计算。但作为一种方法的应用研究和辅助解释还是有价值的。

The sounding data of man made earthquake in Yunnan province is processed by the subwave method. The result shows that there is a clear difference between the reflection mothod and the refraction method. To both horizatial and verticle directions in the crust, the reflect wave is more sensitive than the refraction wave. The factors to affect the width of subwave through the crust are several but not only one, especially in the complexe geological medium of Yunnan province. The result processed by the subwave method is similar to that by the normal method. This method can be of reference value.
