【摘要】:對(duì)長(zhǎng)江以南低山丘陵區(qū)紅壤土岸坡抗侵蝕性能開展定量研究具有重要意義。通過邊坡模型實(shí)驗(yàn),在人工降雨條件下對(duì)紅壤土土工格室護(hù)岸進(jìn)行了不同坡度、不同降雨強(qiáng)度及不同格室類型的降雨沖刷試驗(yàn),對(duì)不同格室的抗侵蝕性能進(jìn)行了定量分析。結(jié)果表明:在該試驗(yàn)降雨條件下,土工格室抗侵蝕性良好,對(duì)紅壤土邊坡的降雨沖刷防護(hù)效果明顯,可在工程實(shí)踐中推廣應(yīng)用。
[Abstract]:It is of great significance to study quantitatively the slope erosion resistance of red loam soil in the hilly region south of the Yangtze River. Through slope model experiments, the erosion tests of different slope, different rainfall intensity and different cell types were carried out on red loam soil under artificial rainfall condition, and the erosion resistance of different lattices was quantitatively analyzed. The results show that the erosion resistance of the geoglass is good under the condition of the experiment rainfall, and the effect of rainfall erosion protection on the red loam slope is obvious, which can be popularized and applied in engineering practice.
