摘要
对筠连地区的岩溶发育特征及地下岩溶管道形成机制进行探讨,认为该地区岩溶发育主要受构造的控制,并在沉积过程中受沉积间断的剥蚀和溶蚀形成了古岩溶通道,与后期构造运动形成的裂缝系统相联通,再经过岩溶水的长期溶蚀,最终形成现在的岩溶管道系统.并由此推断地下岩溶管道路径为:云南延津县下茶坊-高坝-筠连县玉壶井,龙怀坝-莲花坝-筠连县玉壶井.
It discussed the development characteristics of the karst and the forming mechanism of the underground karst pipeline in Junlian region. It holds that the karst development in the region is mainly controlled by structure,and the ancient karst pipeline came into being during the deposition process,denudated and corroded by the sedimentary discontinuity. Connecting to fracture system forming in late tectonic movement,at the same time,long term corrosion of karstic water,the present karst piping system was brought into being. Therefore,the route of underground karst pipeline can be inferred to be: Xiachafang in Yanjin county of Yunnan Province-Gaoba-Yuhujing in Junlian county,and Longhuaiba-Lianhuaba-Yuhujing in Junlian county.
