摘要
阐述了采用声频应力波检测注浆质量的原理、方法,并提出了评价注浆质量的几个参数,通过模型试验和现场检测的数据处理与分析,检测得到的结果与实际破损开的预应力孔道注浆缺陷情况基本一致,表明用声频应力波检测预应力桥梁孔道注浆质量是可行的。
The paper expounds the principle and the method of the audio stress wave to test grouting quality,and puts forward the grouting quality evaluation of several parameters.Through of model-testing and practical examples data processing and analyzing,the paper tells that the test-result is basically the same to defects which the fact damage to prestressed passageways grouting.It shows the method to detect pre-stress bridges grouting quality is feasible.
