摘要

在采石场的飞羽岩开采过程中，碳酸盐单元中的溶洞和潜水通道等岩溶特征的存在可能是极其危险的。迄今为止的几个案例研究表明，探地雷达(GPR)是探测此类特征的合适方法。我们评估了它在探测喀斯特洞穴和不连续性方面的使用，这些洞穴和不连续性可能在Anhovo(斯洛文尼亚西部)rodekv采石场的飞流岩中形成潜在的滑坡表面。我们利用50 MHz非屏蔽粗糙地形天线(RTA)系统记录了3个连续台架的21条GPR剖面，并将其与该地区的构造和岩性填图结果进行了关联。我们定位了几个溶洞，并通过探地雷达剖面的单独解释证实了不连续的存在，但它们与地质和其他数据的相关性使我们对研究地区的构造环境有了更精确的了解。

Analysis of tectonic and karst formations as geological hazard for exploitation of flyschoid rocks by Ground Penetrating Radar, the case of Anhovo-Rodež quarry (W Slovenia)

During the exploitation of flyschoid rocks in quarries, the presence of karst features such as caves and phreatic channels in carbonate units can be extremely hazardous. Several case studies to date have shown that the Ground Penetrating Radar (GPR) is a suitable method for detecting such features. We evaluated its use in detecting karst caves and discontinuities that could form potential landslide surfaces in flyschoid rocks of the Rodež quarry in Anhovo (W Slovenia). We recorded 21 GPR profiles in 3 consecutive benches with the unshielded 50 MHz Rough Terrain Antenna (RTA) system and correlated them with the results of structural and lithological mapping of the area. We located several karst caves and confirmed the presence of discontinuities with the interpretation of GPR profiles alone, but their correlation with geological and other data gave a more precise insight into the structural setting of the studied area.
