摘要
The incremental core-drilling method (ICDM) is a nondestructive technique to assess in-situ stresses in concrete. These stresses may be constant or vary through the thickness of the concrete member under investigation. In this method, a core is drilled into a concrete structure in discrete increments. The displacements that occur locally around the perimeter of the core at each increment are measured and related to the in-situ stresses. This paper presents results from experimental tests in which simple concrete beams were subjected to controlled loads and in-situ stresses measured via ICDM were compared to known stress distributions.
