南洞地下河岩溶管道展布及结构特征的示踪试验解析

运用高精度的示踪试验研究了南洞地下河流域部分岩溶管道的展布状况，并对暗河管道的结构特征进行了分析。试验结果表明：一号暗河有一独立的含水系统，利、给区为瓦白白一带，二号暗河主管道总体通往永宁和石洞方向，三号暗河通往城红寨方向，二号暗河和三号暗河在南洞口附近有连通，枯季时二号暗河补给三号暗河。此外。一号暗河和二号暗河分别呈老年期和壮年期地下河形态，较为畅通；三号暗河则发育较晚，出口处有较多的裂隙。最后，结合现有的资料及流域内的水文地质条件，对流域内岩溶管道的大体分布位置进行了推断，绘制了岩溶管道的展布图，以期为南洞地下河流域的岩溶水文地质调查、物探、钻探及地下水开发利用等提供理论依据。...

The high precision tracer tests were carried out to delineate the distribution of part karst channels in the Nandong underground river drainage and to analyze their structural characteristics. The results show that the No. 1 underground stream has an independent water system, with its recharge area around Wabaibai. The chief channels of No. 2 underground stream are overall towards to Yongning and Shidong. The channels of No. 3 underground stream lead to Chenghongzai. The channels of No. 2 and No. 3 under- ground streams meet each other nearby Nandong outlets where the No. 2 stream supplies No. 3 stream during dry seasons. In addition, No. 1 and No. 2 underground streams present morphology of old and adult ages, re- spectively, and their courses are relatively fluent. Whereas, the No. 3 underground stream developed later and has some cracks nearby its outlet. Finally, this paper infers and maps the general distribut
