公路隧道质量检测是保证其健康状况的重要手段,文章论述了高频电磁场在公路隧道质量检测中的基本原理和测试方法,同时结合工程实例,阐述了此方法应用到检测脱空、空洞、渗漏带、回填欠实、围岩扰动等方面的情况,并对一些典型的隧道检测图像做出了分析与解译。实践表明,应用该技术,可以高效、准确地确定工程隐患位置及大小,定量评价工程质量,为公路隧道设计施工和工程验收提供科学依据。
The quality inspection of highway tunnel is an important means to ensure its health condition. The article discusses the basic principle and test method of high frequency electromagnetic field in highway tunnel quality inspection. At the same time, combined with engineering examples, this paper expounds the application of this method to detect void, void, seepage Leakage zone, backfill owes real, rock disturbance and other aspects of the situation, and some of the typical tunnel inspection images made an analysis and interpretation. Practice shows that the application of this technology can efficiently and accurately determine the location and size of engineering hidden dangers and quantitatively evaluate the project quality so as to provide a scientific basis for the design, construction and acceptance of highway tunnels.
