Surface Penetrating Radar (SPR) Survey is a non-destructive geophysical method used to locate concealed rebar (reinforcing steel) and conduit within structures or concrete surfaces. It uses radar pulses that penetrate the surface and bounce back when encountering objects or interfaces with different electromagnetic properties. By analyzing the reflected signals, SPR can identify the presence, location, and depth of rebar and conduit.

 

SPR survey is very useful for construction projects, especially because of its non-destructive characteristics, as it helps ensure the integrity and safety of structures without the need for invasive probing or drilling.

表面穿透雷達（SPR）測量是一種無損的地球物理測量方法，用於定位建築物或混凝土內部隱藏的鋼筋和管線。它使用雷達脈衝穿透表面，並在遇到具有不同電磁特性的物體或界面時反射不同的回波。通過分析反射信號，SPR可以識別鋼筋和管線的存在、位置和深度。

SPR測量建築項目中十分有用，特別是因為它的無損毀特性可以在不需要入侵性探測或鑽孔的情況下進行測量，確保結構的完整性和安全性。
