多波地震勘探技术在堤防质量探测中的应用
|
摘要
地球物理探测是堤防质量无损探测的重要手段之一。在江西丰城赣江大堤填筑质量探测试验中,采用地震横波反射及纵波折射层析成像勘探方法,取得了良好的效果,探明了大堤缺陷的位置,并对缺陷产生的原因进行了分析。介绍了地震数据的采集方法、资料处理及分析。试验结果表明采用多波地震勘探技术对土石堤坝碾压质量进行探测是可行的。
The geophysical exploration is one of the important means of non-destructive detection of embankment. In the detection and test of Ganjiang River embankment in Fengcheng,Jiangxi Province,by using the tomography technology of S-wave reflection and P-wave refraction tomography,the satisfactory results were achieved,locations of the defects in the embankment were detected and the causes were analyzed. This paper introduces the collection,treatment and analysis method of the data. The test results show that the rolling quality of the earth-rock embankment can be detected by the multi-wave seismic exploration technology.
