Effect of Slope Positions and Years on Three Indexes to Artificial Ecological Substrate

Article Preview

Abstract:

In the region of Hubei Shuibuya hydropower station, the paper studied the variation of slope positions and years to the artificial ecological substrate on Sanyouping highway rock slope by field sampling and office processing. The indexes which were measured and analyzed in experiment mainly included unit weight, water ratio and organic matter. The results showed that the distribution of the three indexes of artificial ecological substrate on the slope were different, and lacked rules to follow. The maximum of unit weight was the middle slope, and the maximum of water ratio was the lower slope, but the organic matter of upper slope was the maximum. As the implementation of ecological restoration project went on, the unit weight of artificial ecological substrate gradually reduced, and the content of organic matter steadily rose, but the water ratio was greatly affected by seasonal rainfall and fluctuated with years. Overall speaking, three kinds of indexes on the slope with the change of years gradually tended to the natural slope. It shows that the rock slope can be restored preferably as long as the ratio of artificial substrate is properly.
