摘　　要：吴家山淤地坝的骨干坝控制流域总面积为30 km2,坝址控制区域属黄土丘陵沟壑区,境内植被稀少,地形支离破碎,沟壑纵横,水土流失严重,年侵蚀模数为11700 t/km2。文章在分析淤地坝工程规模及布置基础上,根据绘制的库容曲线,进行了库区洪水粗调和洪水详调;依据调洪演算计算的下泄洪量,进行了坝高计算,对坝体断面尺寸及筑坝材料进行了设计。The main dam of Wujiashan warping dam controls a watershed with a total area of 30 km2.The control area of the dam site belongs to the loess hilly and gully region,with few vegetation,fragmented terrain,criss-crossing gullies and serious soil erosion,with an annual erosion modulus of 11700 t/km2.On the basis of analyzing the scale and layout of warping dams,this paper makes rough adjustment and detailed adjustment of flood in the reservoir area according to the drawn storage capacity curve.According to the flood discharge calculated by flood regulation calculation,the dam height is calculated,and the dam section size and dam building materials are designed.
