地震波CT在注浆效果检测评价中的应用
|
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,非常适用于工程地质勘查。注浆充填是近几年来应用较多的一种采空区治理方案,由于采空区注浆治理后,其浆液位置和加固效果具有较大的不确定性,因此难以通过传统的取样、密实度等方法进行质量检测。地震波CT以其自身的优势成为了一种注浆质量检测的合适选择,并在实际应用中取得了良好的效果。
The seismic wave CT(Computerized Tomography) is a high resolution geophysical method containing abundant information,and hence it is very suitable for engineering geological exploration.Grouting filling,as a goaf treatment scheme,has been used frequently in recent years.Owing to the considerable uncertainty of the grouting slurry position and reinforcement effect after the grouting treatment,it is difficult to conduct quality examination on the basis of traditional sampling and compactness methods.Due to its own advantage,seismic wave CT has become a suitable choice for grouting quality detection,and it has achieved good results in practical applications.
