| 摘 要： | 定量分析了沟道比降与库容及单位库容坝体土方量的关系,统计了黄土高原陕、晋、内蒙古、宁4省区在建的分布于32条小流域的556座淤地坝的坝体土方量和库容,计算出了这些淤地坝的单位库容坝体土方量,并在此基础上讨论了适宜建坝的沟道比降最大值:坝高分别为10、20、30、40 m时,适宜建坝的最大沟道比降分别为9.55%、8.42%、6.71%、5.57%。 |
| 关 键 词： | 沟道比降 淤地坝 库容 坝体土方量 |

| Abstract: | It quantitatively analyzes the relation between gully slope and storage capacity and earthwork volume of dam body of unit capacity,counts up the earthwork volume of dam body and storage capacity of 556 warping dams distributed in 32 small watersheds that are under construction in 4 provinces of Shaanxi,Shanxi,Inner Mongolia and Ningxia in the Loess Plateau,calculates the earthwork volume of dam body of unit capacity and discusses the maximum value of gully slope where is suitable for building dams based on that condition.When dam height is 10 m,20 m,30 m and 40 m,the maximum gully slope suitable for building dams are 9.55%,8.42%,6.71% and 5.57% respectively. |
| Keywords: | gully slope warping dam storage capacity earthwork volume of dam body |
