建立砒砂岩区坝系相对稳定规模模型的探讨——以内蒙古皇甫川西黑岱沟小流域坝系为例

Exploration on Founding the Pattern in Scale of a Relatively Stable Dam System in Sandstone Area

以位于黄土丘陵沟壑区第一副区砒砂岩区的内蒙古皇甫川流域的西黑岱沟小流域坝系为典例,在坝系相对稳定分析的基础上,利用处于相对稳定的单坝资料,通过回归分析法,推求淤地面积、坝高和控制面积的相关关系,初步分析并建立不同频率暴雨洪水条件下坝系相对稳定的数学模型,探求相对稳定单坝设计及坝系规划的规模依据,以期抛砖引玉、起到推进该地貌类型区坝系相对稳定的研究与实践的作用。

Based on the typical case-Inner Mongolia Xiheidai gully small vallay's dam system that is situated in the first vicearea of the loess hills gully area,and the analysis about the relatively stable dam system,in order to inquire into the interrelation among silt area, dam's height and controlling area, these sinlgedam data were used to be in relative stableness and the mathematical patterns of relatively stable dam system under different conditions for torrential rain frequency was found through regression analysis,and the scale basis for relatively stable singledam design and dam system plan as well. It will play a part in advancing research and practice about relatively stable dam system in the same geomorphologic area.
