基于声学传播特性的埋地管道探测技术研究

Research on Buried Pipeline Detection Technology Based on Acoustic Propagation Characteristics

目前,金属管道探测技术较为成熟、精度较高,而对于非金属管道探测尚没有较好的测量方法,且检测成本较高。文中通过研究声波在管道、液体和土壤中的传播特性和差异性,提出了基于声学传播的埋地管道探测方法。该方法基于地面振动进行地下管道检测,可以提高检测效率和准确率,在工程实践中具有很大的实用价值。

At present, the metal pipeline detection technology is relatively mature with high accuracy, while there is no stable measurement method for non-metallic pipeline detection, and the cost is rising. By studying the propagation characteristics and differences of sound waves in pipelines, liquids and soils, this paper proposes a buried pipeline detection method based on acoustic propagation. This method can improve the efficiency and accuracy of underground pipeline detection based on ground vibration, and has great practical value in engineering practice.
