Evaluating the Infrared Heat Method’s Ability to Detect "Air Escape" under Dyke and Dam Concrete Roof Slabs

Abstract

Over time, "air escape" appears in irrigation works in general and in concrete-face rock- fill or concrete roof slab dams in particular. These "air escapes" (hollow layers), if not found and dealt with in time, will greatly affect the upper layer of a dam, cause soakage, leakage and shorten the life span of the structure. The paper discusses several new results obtained from applying the Infrared Heat method to assess its ability to detect "air escape" under dyke and dam concrete roof slabs.

Keywords
