Terminating industrial activities may have harmful side effects on the infrastructure of a civil society. One effective method of solving environmental and geotechnical problems in urban areas is a direct‐current resistivity survey. In karstic areas, large‐scale geological structures directly affect the near‐surface, small‐scale events. Reliable data on the geological background of harmful events are acquired through suitable combinations of large‐scale and of small‐scale high‐resolution surveys. In this study, the geological background of three urban subsurface‐related problems was investigated in a karstic area: collapse of a sinkhole, suffusion of a basement area, and contamination of an urban creek. In each case, the scientific work aimed at setting up of a suitable model that describes the harmful event and its geological background. For this purpose, a combination of large‐scale and high‐resolution resistivity data was acquired and augmented by borehole information and laboratory analyses. The error analyses of the resulting models suggest that the methodology of dual‐scale geoelectric investigation of urban hazards in karstic areas can provide applicable models for mitigation measures.

直流电阻率法在岩溶地区城市地质问题中的应用

终止工业活动可能会对公民社会的基础设施产生有害的副作用。解决城市地区环境和岩土工程问题的一种有效方法是直流电阻率测量。在岩溶地区，大规模的地质构造直接影响到近地表的小规模事件。通过适当组合大型和小型高分辨率调查，可以获取有关有害事件地质背景的可靠数据。在这项研究中，研究人员在一个岩溶地区研究了三个与城市地下有关的问题的地质背景：塌陷，地下室布满以及城市小溪的污染。在每种情况下，科学工作都旨在建立一个描述有害事件及其地质背景的合适模型。为此，通过井眼信息和实验室分析获得并结合了大规模和高分辨率电阻率数据。结果模型的误差分析表明，对岩溶地区城市灾害进行双重规模地电调查的方法可以为缓解措施提供适用的模型。
