Abstract
Laguhe Reservoir in Yunnan is a medium-sized reservoir dominated by farmland irrigation. The site selection of the reservoir is limited by topographic geological conditions. The reservoir area is located in the soluble rock strata of the Sinian Dengying Formation. The soluble rock below the normal water storage level accounts for over 98%.There is a low-alloy valley Lama River on the side, and the karst seepage problem in the reservoir area is the key factor for the success or failure of the reservoir. By analyzing the karst development characteristics and karst development control factors, the spring spot exposure law, the spatial distribution of the relative aquifer and the hydrogeological exploration data, it is concluded that the reservoir water will not generate large-scale karst seepage into the surrounding and low neighboring valleys. Leakage, reservoir construction conditions are established. The reservoir has been completed and put into operation, and the water storage in the reservoir area is normal. The verification results are consistent with the analysis conclusions, which provides reference for the study of reservoir construction in large-area soluble rock areas.关键词
