摘 要:地下管线作为市政建设的重要配套项目,承担着供水、供气、排水、排污和电力通讯等诸多功能。在漫长的城市化发展中,地下管线的建设资料往往存在遗失、难找寻的问题,导致城市在改扩建过程中无法确定地下管线的位置,在施工过程中可能会误破坏已有管线,对居民的正常生产生活造成不便,所以对于地下管线的探测定位就显得极为迫切。针对地下管线探测,借助于虚拟仪器技术搭建了一套利用瑞雷波探测地下管线的探测系统,并在埋有地下管线的实验地点进行地下管线的探测实验,实验结果表明,该系统在地下管线探测方面具有较好的应用前景。

Abstract: As an important supporting project of municipal construction, underground pipelines undertake many functions such as water supply, gas supply, drainage, sewage and electric power communication. In the long-term urbanization development, the construction materials of underground pipelines often have problems that are lost and difficult to find,it causes the location of underground pipelines to be determined during the process of urban reconstruction and expansion, which may be damaged during the construction process. Therefore, it is extremely urgent to detect and locate underground pipelines. Aiming at the detection of underground pipeline, a set of detection system using Rayleigh wave is set up by means of virtual instrument technology.And the detection experiment of underground pipeline is carried out in the experimental site where underground pipeline is buried. Experimental results show that the system has a good application prospect in the detection of underground pipeline.

在城市发展过程中,地下管线作为供水、供气、排水、排污和布设电力通讯线缆的通道,如同城市的生命线一般。中国的城市地下管线长度十分惊人,像北京、上海这样的特大城市,地下管线长度可以达到10万km左右,即使是一般的县城,其地下管線长度也能达到近1 000km。但是,在我国城市化发展中,人们往往重建设、轻管理,不同的城市建设部门对于地下管线的管理各自为政,没有形成统一规范的规划、报建、审批、勘测、验收备案以及资料归档管理,地下管线管理基本处于无序状态。在后期城市建设与改造中,由于管线档案资料缺失,引发了很多管线破坏、停电停水等诸多事故,给社会经济生产和居民正常生活造成了极大不便[1]。……
