摘　　要：由于单一物探方法的局限性,地下管线的探测精度已难以满足目前岩土工程施工的要求。通过对管线仪特征比值定深法的分析,获取了特征比值与管线深度变化的关系;以此将探地雷达与管线仪探测数据建立起联系及相互约束关系,提出了二种探测数据的联合反演解释方法,并采用可视化编程工具实现了相应的综合解释模块。数值模型及现场实测数据的解释结果均表明,在反演过程中实现两种物探方法的综合解释,明显地提高了对地下管线埋置深度及水平位置的判定精度。The detection accuracy of underground pipelines had already been difficult to satis- fy the needs for Geo--technical engineering construction because of the limitation of single geophysical survey method. By analyzing the characteristic ratio method of calculating underground pipeline depth, the relation between characteristic ratio and pipeline depth was obtained. Based on these discussions, the restriction relation was set up between Ground penetrating radar and pipeline locator detecting data, and we brought forward the joint inversion interpretation method using the two geophysical survey data. And also the comprehensive in- terpretation module was carried out using Visual Basic tools. Interpretation results of numerical simulation model and filed testing show that joint inversion comprehensive interpretation can improve the resolution of underground pipeline depth and position.
