| 摘 要： | 利用堆积物启动的最小坡度公式,求出喇嘛溪沟堆积物启动的最小坡角,结合其纵断面图阐述修筑谷坊坝对原流域侵蚀的影响;绘出无拦沙坝时沟道自然淤积纵断面、修拦沙坝后沟道淤积纵断面、人工填土与修拦沙坝共同作用时沟道淤积纵断面并进行三断面的对比,研究填方反压前后对沟道物质淤积的影响情况。

| Abstract: | With the minimum grade formula initiated from deposition,this paper has acquired the minimum grading angle initiated from deposition in Nama Channel.Combined with its vertical section picture,it describes the influence on the erosion of original valley by building of check dam;depicts the vertical section of valley natural accretion before building sediment control dam,that of after building sediment control dam,and that under interaction of artificial earth filling and sediment control dam,as well as carri... |
