滇东南马关县坡脚镇渔塘暗河发育特征及对工程影响的分析

Analysis on the Development Characteristics of the Yutang Underground River and Their Effects on Engineering in Pojiao Town of Maguan County, Southeast of Yunnan Province

暗河对于地下水资源的开发保护和岩溶地区的地质工程稳定性评价有十分重要的科学意义与经济价值,其研究亦对暗河水库工程顺利建设与施工有着重要的指导价值。结合详细的野外调研,对马关县坡脚镇季节性天然湖泊拟建库区的地质构造、地层岩性、水文地质条件和工程地质条件进行了分析。基于以上条件,分析了暗河的形成条件、空间展布、主通道和渗漏等特征,为拟建暗河水库工程提供科学的理论依据。

Underground river has very important scientific significance and economic value for the development and protection of groundwater resources and the stability evaluation of geological engineering. The research of the underground river also has an important guiding value for the construction and build smoothly of the underground reservoir. Combined with detailed field investigation, it analysed the reservoir area of seasonal natural lakes in Pojiao town at Maguan County, such as the geological structure, lithology, hydrogeological conditions and the engineering geological conditions. Based on these conditions, it analyzed some characteristics, such as the formation conditions, spatial distribution, main channel and leakage of the underground river, and it provided scientific theory foundation for the proposed underground river reservoir project.
