slope of grain

The grain size characteristics and the content of the sediments are controlled mainly by the hydrodynamic environment, topographic slope and transportation distance.

不同河段沉积物粒度及其含量的变化主要受水动力条件、地形坡度和搬运距离控制，但搬运距离与沉积物粒度之间不存在简单的线性对应关系。

Through studying on the control experiment of the coarse-grained soil permeation damage slope of different grain composition, the paper points out that there is relativity between the scope of permeation damage and its grain composition of course-grained soil.

通过对粗粒土不同级配的渗透破坏坡降控制性试验研究，发现粗粒土的渗透破坏坡降与其级配在不同范围内存在一定的相关性联系。

Because the grain is little in full tailings, angle of beach surface slope become very smooth near the gateway, and the flow is very slow. Remain the slowly sliding flow, so angle of beach surface is about 0.3%.

但由于全尾矿中这种颗粒少，离放矿口不远处的滩面坡度就变的很平缓，流速很慢，维持这种缓慢滑移流动的滩面坡度约为0.3%。
