地质雷达无损探测技术在新疆阜康白杨河水库隧洞衬砌检测中的应用

Application of Geological Radar Non-destructive Detection Technique in Xinjiang Fukang Baiyanghe Reservoir Tunnel Lining Detection

本文简要介绍了地质雷达检测水利工程隧洞质量的基本原理和方法,并结合实际,通过对新疆阜康白杨河水库导流洞混凝土衬砌检测的地质雷达图像进行分析,直观反映出隧道衬砌厚度、空洞及内部钢筋的分布等特征。结果表明,地质雷达检测技术能够直观地反应出工程隧洞内部结构,进而可以准确地查出混凝土结构内部缺陷的类型和位置,为后期修补提供技术支持。

The basic principles and methods for detecting hydraulic project tunnel quality by geological radar are briefly introduced in the paper. The geological radar images for detecting Xinjiang Fukang Baiyanghe Reservoir Water Diversion Tunnel Concrete Lining are analyzed by combining with actual situation for directly reflecting tunnel lining thickness, hollowness, inner steel bar distribution and other features. The results showed that the internal structure of project tunnel can be directly reflected by geological radar detection technology, thereby accurately checking the types and positions of concrete structure internal defects, and providing technical support of subsequent repair.
