| 随着科学技术的发展,地球物理勘探方法已在各类地下管线探测中得到了广泛应用。本文叙述了探地雷达法和高密度电法对城市燃气管道进行联合勘察的应用案例。探地雷达法可以快速、有效查明地下介质的密实性情况,对地下疏松体、燃气管道等介质突变界面有较好的纵向分辨能力;高密度电法可以直观地反映地下物质电性界面在横向上的差异,适用于物性边界层位划分和电性不连续面的判定。两种物探方法的综合应用基本探明了新建地下管线的位置和埋深,排查出了场地下方的土体病害情况,取得了较好的勘察效果,为新建工程后续施工提供了重要依据。 |
| 英文摘要: |
| With the development of science and technology geophysical methods have been widely applied in various underground pipeline detections. The article describes in detail the application of the integrated ground penetrating radar and high-density electrical methods to gas pipeline survey. The ground penetrating radar method can quickly and effectively identify the compactness of underground media with good vertical resolution for sudden changes in media interfaces,such as underground loose bodies and gas pipelines; the multi-electrode resistivity method can directly reflect the horizontal differences of the electrical interfaces of underground materials,and is suitable for the division of physical boundary layers and the determination of electrical discontinuities. The comprehensive application of these two geophysical methods has basically determined the location and burial depth of newly built underground pipelines in the work area,and has also identified soil diseases in the underground area. The mentioned above achievements provide important technical support for the subsequent construction of new projects. |
