摘要
经调查研究认为源头地下河系统汇水面积13.25 km2,主要发育于岩溶发育的D2d、D3r地层中,主干段长度4.5 km,源头岩溶水系统岩溶地下水主要由南东向北西、由两侧向中间地下河主管道径流汇集。主干地下河的侧支径流地下河或岩溶径流管道有蚂拐岩地下河、天河玉———大浪———响水岩北侧径流管道、天井南西侧径流管道、岩山咸———源头径流管道,同时对该地下河系统的补径排条件、边界条件、地下水赋存条件等进行了分析。
After field investigation and analysis, a conclusion is drawn that the water collecting area is 13.25 km^2 in Yuantou underground river system. It mainly distribute in karst developed D2d and D3r Formation, the strem ranged about 4.5 km, The karst underground water in Yuantou karst water system converged mainly from the southeast to the northwest and from the symmetry portion to the underground river＇ s main pipeline. The stem underground river＇ s lateral runoff buried river or karst runoff pipeline contains Maguaiyan underground river, Tianheyu——Dalang{Xiangshuiyan northside runoff pipeline,Tianjing southwest side runoff pipeline, Yandan——Yuantou runoff pipeline. Besides the paper analysised the hydrogeological features in this underground river system.
