豫北太行山南缘寒武系碳酸盐岩地层分布广泛,区内分布有众多的水利水电工程,岩溶发育特征与水库渗漏条件密切相关。文章通过区域岩溶水文地质调查,从地质构造背景、地层沉积环境的形成演化及岩性、岩体透水性等影响岩溶发育的主要控制因素入手,结合区内河口村水库、蟒河口水库等相关水库的勘察实践,系统总结了区域岩溶形态、规模、发育规律及其空间分布特征,提出豫北太行山南缘寒武系碳酸盐岩地层中与水库渗漏密切相关的岩溶现象以现代河谷岩溶为主,相应的水库渗漏形式为裂隙型或裂隙管道混合型为主,为水库防渗处理方案提供了地质依据。
The Cambrian carbonate rocks in the southern margin of the northern Taihang Mountains in North Henan are widely distributed. There are many water conservancy and hydropower projects distributed in the area. The developmental characteristics of karst are closely related to reservoir seepage conditions. Based on the investigation of regional karst hydrogeology, starting with the geological structure, the formation and evolution of sedimentary environment, and the main controlling factors affecting the karst development, such as lithology and permeability of rock mass, the paper combined with the related reservoirs such as Hekoucun reservoir and Pythonhekou reservoir The karst phenomenon closely related to reservoir seepage in the Cambrian carbonate strata on the southern margin of the Taihang Mountains in the northern part of the country is proposed. The karst in modern valley is The main reservoir leakage is mainly of fissure type or fissure pipe type, which provides the geological basis for reservoir seepage control treatment.
