摘　　要：针对酥油口水库坝址区较复杂的工程地质条件,从地形地貌、地层岩性、地质构造、岩体物理力学性质及透水性等方面,对坝址区地质环境各因素及各种坝型适宜性进行分析论证,结合当地天然建筑材料优势,最终选择技术和经济均较优的沥青砼心墙砂砾石坝坝型方案。In view of the complex engineering geological conditions in the dam site area of the yak youkou reservoir, the factors of the geological environment and the suitability of various dam types are analyzed and demonstrated from the aspects of geomorphology, lithology, geological structure, physical mechanical properties and permeability of the rock body. Combined with the advantages of local natural building materials, the gravel dam type scheme of asphalt concrete core wall sand dam with better technology and economy was selected.

关 键 词：地质条件 坝型选择 沥青砼心墙砂砾石坝
