摘　　要：河口村水库工程库坝区地质条件与水文地质条件复杂。通过对库坝区地质构造、岩溶发育及岩体透水性等基本工程地质条件的分析可知,库坝区疙料滩—谢庄一线的下游库岸存在多处渗漏段,总渗漏量较大,此外坝基河床存在深厚覆盖层,左岸存在龟头山山体失稳及变形问题,这些工程地质问题对河口村水库工程设计和建设影响重大。The geological and hydrogeological conditions of Hekoueun reservoir area are complex. The basic engineering geological conditions such as the geological structure, karst development and rock permeability were analyzed in this paper. The analysis shows that there are several seepage sections along the reservoir banks in the downstream regions of Geliaotan - Xiezhuang, and the total leakage of these sections is great without the seepage control measures. Moreover, the deep riverbed alluviums problem exists in the dam foundation, and mountain stabilization and deformation preblems exist at Guitou Mountain the left bank. These engineering geological problems have humongous influence to the design and construction of Hekoucun Reservoir.
