摘要：

分析流量衰减曲线是研究岩溶含水层水文地质参数的重要手段。在阐明流量衰减分析理论的基础上,通过连续监测一年寨底地下河出口的小时流量过程,共获取8 784组流量数据。首先选取典型的2013年9月25日3:00暴雨后至2013年10月13日17:00的446组流量数据作为研究对象,并利用MATLAB软件对该时间段的流量过程进行曲线拟合,从而确定了不同阶段流量衰减系数分别为0.642 5、0.025 8、0.001 5;然后通过流量衰减系数计算寨底不同含水介质导水系数T与给水度S的比值;最后利用裂隙率近似给水度的方法确定了寨底不同含水介质的水文地质参数。结果表明,寨底岩溶管道、裂隙、基岩介质导水系数分别为:258.87、3 865.98、40.64 m²/d。说明辅以必要的水文地质调查,确定管道分布和径流距离,流量衰减曲线可用于计算岩溶含水层不同介质的导水性能和给水度。

Abstract:

Analysis of flux recession process is an important method to calculate hydrogeological parameters of karst aquifers. Based on the theoretical method of flux recession analysis, the author took the flux records from Sep.25th to Oct. 13th, 2013 as samples out of the total 8 784 sets of flux data through monitoring the export of underground river per hour throughout the whole year to fit flux recession process by MATLAB; and then the attenuation coefficients of three phases were obtained as 0.642 5, 0.025 8 and 0.001 5 respectively; at last, the ratios of hydraulic conductivity to specific yield were calculated, and the hydrogeological parameters were confirmed by given cranny ratio which was roughly equal to the specific yield. The result shows that the hydraulic conductivity for karst conduit, fissured and bedrock medium in Zhaidi basin were 258.87 m²/d, 3 865.98 m²/d, and 40.64 m²/d respectively. With the requisite hydrogeological survey, defined conduit distribution, and runoff distance, the method of flux recession analysis could be used to calculate the conductive capability and specific yield of different media for a karst aquifer.
