Abstract
The quality of anchor rod support in underground caverns is related to the overall stability of the surrounding rock mass of the project,and is also an important basis for the quality evaluation of unit engineering.In order to efficiently detect anchorage quality,non-destructive testing technology has become the preferred method for anchorage quality inspection.Multiple comprehensive experimental studies were conducted on the selection of long anchor rods before the construction of rock wall beam anchor rods for a pumped storage hydropower station in Henan.This paper compares and analyzes the results of non-destructive testing with the observation and testing results of pipe cutting.The results indicate that factors such as longer exposed anchor rods,anti-corrosion treatment of anchor rods,mortar strength,and testing methods have a significant impact on the determination of anchor rod length and grouting density using non-destructive testing technology.The original non-destructive testing data needs to be corrected through experiments.关键词
