基于降落漏斗曲线方程的西南岩溶区地下导水通道预测
Prediction of underground water channel in southwest karst area based on depression cone curve equation
摘要
Abstract
[Objective]In order to investigate the potential existence of karst water channels within the depression cone area,and to provide solutions for addressing collapse risks in karst regions and groundwater flow issues near inadequate waterproof or inter-mittent curtains,[Methods]taking the Panlong lead-zinc mine area in Guangxi as a case study,the theoretical value(difference)of the water level at the observation point is calculated using the descending funnel curve.By comparing and analyzing the differ-ences between the theoretical and measured(difference)values,along with on-site drilling and collapse data,a prediction of the underground water channels in the karst region will be made.[Results]The result prove that the proposed method can accurately predict the karst water channel.[Conclusion]In a karst aquifer that forms a stable depression cone,when the measured water level of a borehole is lower than the theoretical value(hMeasure＜hTheory),or when the measured difference exceeds the theoretical difference(ΔhMeasure＞ΔhTheory),it indicates the presence of a karst water channel at the borehole.The concept of the landing fun-nel is introduced,suggesting that the relative aquifuge within the influence range of the funnel alters the horizontal distance of the measurement points outside the aquifuge.The adjusted distance should be represented as l+r.The diffraction characteristics of the cone of depression can indicate the presence of runoff channels within the adjacent aquifuge.关键词
