地震波CT应用中触发器的改良
|
摘要
地震波CT(Computerized Tomography)是一种信息量大、分辨率高的地球物理方法,被广泛应用于注浆效果检测中。在实际应用过程中,原始数据的采集质量,直接影响到此方法的应用效果。该方法的触发器目前在国内未有较成熟稳定的装置,因此触发器成为数据采集好坏的关键因素。本文结合具体注浆检测项目,对比试验,分析总结各种触发器优缺点,并通过实际应用,最终改良出一套稳定触发器,得出良好的检测效果。
Seismic wave CT(Computerized Tomography) has the features of a large amount of information and high resolution,which is widely used in the grouting effect detection.In practical application,the original data acquisition quality directly affects the effect of the application.At present,there is not a stable device for the trigger in this method at home,so the trigger becomes the key factor in the data acquisition.Combining the grouting detection project,the experiment is compared in this paper and the advantages and disadvantages are analyzed.Through the practical application,a set of stable triggers are reformed and a good result is achieved.
