Nondestructive Techniques for Inspecting Concrete Dams and Spillways

摘要

Periodic inspections of aging concrete structures are useful for identifying concrete degradation before it becomes a serious problem. Where visual inspection is impractical or impossible, nondestructive evaluation methods can be used. Three such methods — spectral analysis of surface waves, ground penetrating radar, and acoustic tomography — are particularly useful in dam and spillway inspections.
