反向VSP透射层析成像法在岩墙松动层检测中的应用

THE APPLICATION OF PSEUDO?VSP METHOD TO THE DETECTION OF LOOSENED ZONE IN QUARRY WALL

通过实例介绍了反向VSP透射层析成像方法的基本原理、数据采集和资料处理方法。利用该方法在检测岩墙松动层厚度中取得了很好的勘探效果。

The Pseudo Vertical Seismic Profiling, somewhat similar to vertical seismic profiling, was successfully applied in detecting the loosened zone of quarry wall. The seismic transmission wave tomography was used to process the data. The basic theory, data acquisition and processing as well as case history are dealt with in this paper.
