Abstract

Due to the complex karst geological structure, the construction of diversion aqueducts in karst formations poses deformation and stability challenges for the foundation. During the construction of the aqueduct in Jifu Village, Yunnan Province, a comprehensive detection method was employed to investigate the karst development in the area. This method integrates information obtained from various techniques, including geological analysis, Ground Penetrating Radar (GPR), and drilling. Geological analysis was used to identify potential karst development locations within the project area. GPR provided geophysical profiles revealing shallow karst features, and drilling was strategically placed along these profiles to verify and supplement the GPR data. This approach yielded more accurate information on karst development. The results demonstrate that the combination of geological analysis, geophysics, and drilling can effectively detect karst formations. The identified karst locations were consistent with the inferred underground karst zones from the investigation. Optimizing and refining this method can offer valuable reference and guidance for detecting karst areas in similar regions.

导流渡槽岩溶发育特征综合检测方法与评价——以云南为例

由于岩溶地质构造复杂，在岩溶地层中修建导流渡槽对地基变形和稳定性提出了挑战。在云南吉府村渡槽施工过程中，采用综合检测方法对该地区岩溶发育情况进行了调查。该方法综合了各种技术获得的信息，包括地质分析、探地雷达（GPR）和钻井。通过地质分析，确定了项目区内潜在的岩溶发育位置。GPR提供了揭示浅层岩溶特征的地球物理剖面，钻井沿着这些剖面进行，以验证和补充GPR数据。这种方法获得了更准确的喀斯特发育信息。结果表明，地质分析、地球物理和钻井相结合，可以有效地探测岩溶地层。识别的岩溶位置与调查推断的地下岩溶带一致。对该方法进行优化和细化，可为类似地区的岩溶区探测提供有价值的参考和指导。
