Abstract: To comprehensively evaluate the quality of the anti-abrasion concrete structure in the bottom plate of stilling basin of a hydrojunction, we combine geophysical exploration, core drilling, and indoor testing techniques for comprehensive testing. We sequentially complete the positioning, core sampling, recording, panoramic digital imaging of boreholes, and physical and mechanical property testing of core samples, to obtain data on the appearance, wave velocity, density, water absorption, and compressive strength characteristics of concrete structure core samples in a small-invasive manner. Based on design and regulatory requirements, a comprehensive analysis is conducted on all testing data, and the results show that the upper anti-abrasion concrete is unqualified and the bottom concrete meets standards. The application effect of this integrated detection is significant, providing scientific basis for quality assessment and can serve as a reference for similar projects.
