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。 Computerized Tomography (CT) is a geophysical method with large amount of information and high resolution. It is widely used in the grouting effect detection. In the actual application process, the quality of the original data acquisition directly affects the application effect of this method. At present, the trigger of the method does not have more mature and stable devices in China, so the trigger becomes the key factor of data collection. In this paper, the specific grouting test items, comparative tests, analysis and summary of the advantages and disadvantages of various triggers, and through practical application, and ultimately improve a set of stable trigger, come to a good test results.
