一、坝址地质1.地形响洪甸水库位于淠河西源,壩址位于麻埠下游约8公里的响洪甸。自壩址逆流而上,两岸山势雄伟,形成峡谷,出黄石冲口后即豁然开朗,为一冲积平原,天然形成良好的水库腹地。水库四周群山环抱,山岭重迭,构成良好的分水岭。壩址附近河道宽度一般为150～200公尺,河床比降由1/800～1/1000,两岸 First, the dam site geology 1 terrain ring Hongdian reservoir is located in the west source of Bahe, Dam site is located about 8 km downstream of Meadow Harbor Hong Austin. Since the upstream of the dam site, both sides of the mountain have majestic mountains and valleys, forming a canyon. After the Yellowstone blurted out, it became an alluvial plain that naturally formed a good hinterland of the reservoir. Surrounded by mountains surrounded by mountains, mountains overlap, constitute a good watershed. The width of the river near the dam site is generally 150 to 200 meters, the river bed ratio by 1/800 ~ 1/1000, both sides
