小能量电火花震源能量偏小的现状影响了其在地层弹性波CT的广泛应用。分析了便携、大功率、激发能量可控震源激发系统研制的必要性，介绍了研制的1万焦耳大功率ZDF-3型电火花震源及其配合地震仪在跨孔弹性波CT探测中的应用，列举了两个地基CT检测实例，说明大跨孔CT检测其成本远低于传统小跨孔CT检测。显示了应用大功率电火花做震源的大跨距CT探测的良好应用前景。

The limited power of small energy sparker has confined its wide application on the elastic wave CT in layered medium. This paper introduces the ZDF-3 type high-power sparker as well as its application in cross-hole elastic wave CT, aided by seismic instruments. Two examples of ground-based CT were demonstrated, showing that the cost of large-distance CT detection was lower than the traditional shot-distance CT detection. This study indicates that the ap-plication of high-energy sparker of the large cross-hole CT has a good prospect.
