高密度电阻率法在厂口隧洞检测中的应用

The High-Density Resistivity Method Apply in Changkou Tunnel Testing

介绍了在昆明厂口隧洞开挖中发生隧洞拱顶上方岩体开裂、坍落、变形的情况下,用高密度电阻率法对隧洞区域地表以下地质情况和含水情况、地表至隧洞之间塌方体的空间形态以及开挖的前方工程地质结构情况进行勘察,并根据对所得数据的处理和分析得出物探结论,为隧洞衬砌修复提供了科学依据。

Cracking, collapse and deformation happened to the rock upward side of Kunming Changkou tunnel vault, using high-density resistivity method to detecting the geologic and watery situation on and under the earth＇s surface, the space shape of the collapse body between the earth＇s surface and tunnel as well as the geologic structure situation ahead of the digging project are detected, according to the settlement and analysis of the data, geophysical prospecting conclusion is get, scientific proof is given to tunnel lining repair.
