从对冲击回波法原理的研究出发,笔者对冲击回波法测试预应力管道内压浆密实度的多种结果比对分析,并进行实体验证,直观的反映冲击回波法的准确性,可对今后的检测过程中起指导作用。
Starting from the research of the principle of impact echo method, the author compares and analyzes many results of the impact echo method for testing the compaction degree of the grout in the prestressed pipeline, and verifies the accuracy of the impact echo method intuitively. Can play a guiding role in the future testing process.
