中文摘要：
基于地质雷达探测原理，论证地质雷达用于复杂公路管线探测的可行性。针对北京望京地区复杂公路，采用SIR-20型地质雷达对施工面地质情况、管线平面位置和埋深进行实测，探测结果表明：相对介电常数较大的目标体吸收周围介质的电磁波信号；最大反射雷达波强度出现在管线顶部；底部产生的雷达波图像中“弧形”宽度大于顶部。基于以上研究，提出针对复杂公路管线探测的设计方案及事故处理措施，同时结合现场制定地质雷达测试热力管线方案。研究结果验证了利用地质雷达探测热力管线的可行性，为后续安全动态施工设计提供了依据，也为地质雷达在复杂公路管线探测方面积累一定的经验。
英文摘要：
Based on test principle of ground penetrating radar （GPR）, the application feasibility for detecting the heating pipelines on complex highway is verified. In accordance with the complex highway in Wangjing area of Beijing, by using ground penetrating radar of SIR-20 to monitor the geological situation of construction surface, the plain position of pipeline and the buried depth, the detection shows that ： the objects of bigger relative dielectric constant absorbs the e- lectromagnetic wave signal from periphery ; the maximum intensity of reflection radar wave appears at the top of pipeline ; the ＂arc＂ width in radar wave image produced by the bottom of pipeline is bigger than the top. Based on these studies, the design program and accident removal countermeasures for the detection of complex highway pipeline are proposed. Meanwhile, combining with actual measurement in field, contrives scheme utilizing ground penetrating radar to detect heating pipelines. It could be verified the feasibility of testing heating pipelines with ground penetrating radar,provides a basis for the subsequent security dynamic construction radar detecting pipeline on complex highway.
