罗甸县木引镇引水工程水源岩溶发育规律分析

Analysis on karst development of water source in water diversion project in Muyin Town, Luodian County

罗甸县木引镇引水工程引用水源为打高暗河地下水,属从里暗河系统,为岩溶管道水。工程区内广泛分布灰岩、白云质灰岩、灰质白云岩、白云岩等可溶碳酸盐岩,发育打狼背斜及水塘向斜、妹场断裂等。本文对引水水源岩溶水文地质条件进行了研究,调查分析结果表明:岩溶发育强度、规模及范围受岩性控制,发育的方向受地质构造控制,受地貌影响。该工程引水水源的岩溶发育规律研究成果,对贵州喀斯特山区饮水工程的建设具有借鉴意义。

Underground water of Dagao underground river is adopted as the water source in the water diversion project of Muding Town in Luodian County, which belongs to Congli underground river system and karst pipeline water. Soluble carbonate rocks such as limestone, dolomitic limestone, limestone dolomite and dolomite are widely distributed in the project area. Dalang anticline, pond syncline and Meichang fracture, etc. are available. The karst hydrogeological conditions of the water diversion source are studied in the paper. The investigation and analysis results show that the intensity, scale and scope of karst development are controlled by lithology, the direction of karst development is controlled by geological structure and influenced by geomorphology. The research results of karst development rule of the water diversion source of the project have reference significance for the construction of drinking water project in karst mountainous areas of Guizhou.
