摘要:
隐伏岩溶因其隐蔽性强和发育无规律性等特点,给岩溶地区的铁路建设和运营带来极大的安全隐患,寻求高效精准的探测方法是隐伏岩溶勘察的重难点。利用岩溶与其周围岩体之间的物性差异,物探方法对隐伏岩溶有较好的探测效果。地质雷达法因其高效、无损、低成本等优点,近年来被广泛应用于铁路、公路和城市等地下隐伏岩溶的探测工作。本文以在建贵南高速铁路为背景,应用两种地质雷达设备对某岩质边坡隐伏岩溶进行探测,详细对比了两种不同地质雷达仪器的探测成果,并将探测成果进行了开挖验证。结果表明:两种地质雷达设备在隐伏岩溶地质体勘察中均能得到较好的探测效果。研究成果可为类似隐伏岩溶探测工作的设备选择提供参考。
Abstract:
Concealed karst poses significant safety hazards to railway construction and operation in karst regions due to its strong concealment and irregular development. Seeking efficient and precise detection methods is a crucial challenge in concealed karst exploration. Geophysical methods,leveraging the physical property differences between karst and surrounding rock masses,exhibit excellent detection capabilities for concealed karst. Among these methods,the ground penetrating radar(GPR)technique has been widely applied in recent years for detecting concealed karst beneath railways,highways,and urban areas due to its high efficiency,non-destructive nature,and low cost. This paper takes the ongoing construction of the Guiyang-Nanning High-speed Railway as a case study,utilizing two types of GPR equipment to detect concealed karst within a rocky slope. A detailed comparison of the detection results obtained from the two GPR systems is presented,and the results are further validated through excavation. The findings indicate that both GPR systems achieve satisfactory detection outcomes in the exploration of concealed karst geological bodies. This research provides valuable insights for equipment selection in similar concealed karst detection tasks.
