摘要: Shield tunnel requires routine inspections for construction safety and quality control. The rapidness, non-destructiveness high precision of GPR 3D laser scanning technology enable them to be widely increasingly used in detection. evaluation Yingbin No.3 Road Tunnel is presented this paper illustrate the application inspection on thickness grouting layer behind segment testing surface situation liner. advantages limitations above-mentioned two methods are discussed suggestions provided.
