摘要:
岩溶塌陷的发生具有突发性和隐蔽性，采取有效方法准确识别潜在致塌位置对科学合理防治岩溶塌陷具有重要意义。以武汉市典型地区为实例，对比分析了丰水期和枯水期地质雷达、高密度电阻率法、静力触探3种勘探方法对岩溶塌陷的探测效果。结果表明：在该类地质条件下，地质雷达在工作频率≤100 MHz时，对4 m以内的扰动土有明显的响应，40 MHz工作频率的探测深度枯水期大于丰水期，100 MHz工作频率的扰动土响应特征枯水期比丰水期明显。高密度电阻率法在丰水期对地层结构的刻画更为精细准确，适用于浅中层岩土体结构探测。静力触探在丰水期和枯水期无显著差异，适用于10 m以内土体探测，尤其适用于圈定塌陷区边界范围。研究结果可为水动力条件季节性变化大的地区其岩溶塌陷探测方法的选择提供参考，为潜在塌陷点的准确识别提供技术支撑。
Abstract:Karst collapse geological disaster seriously restricts the social development. Due to its sudden and concealment, it is of great significance to take effective methods to accurately identify the potential collapse location for the scientific and reasonable prevention and control of karst collapse. In this study, a typical area in Wuhan was taken as an example to compare the karst collapse detection effects of three exploration methods, namely ground-penetrating radar (GPR), high-density resistivity method, and cone penetration, in rainy and dry seasons, providing reference for the selection of karst collapse exploration methods under hydrodynamic condition changes. The results show that the GPR has a good response to the disturbed soil within 4 m at the frequency of ≤100 MHz. The detection depth of 40 MHz GPR is deeper, and the abnormal response of the disturbed soil detected by 100 MHz GPR is clearer in dry seasons than that in rainy seasons. The high-density resistivity method describes the stratigraphic structure more accurately in rainy seasons than in dry seasons, and is adaptable for the detection of shallow and middle rock and soil structure. There is no significant difference between cone penetration in the period of rainy and dry seasons, while that is suitable for soil detection within 10 m, especially for delineating the boundary range of the subsidence area.
