| 摘 要： | 为了对红层软岩生态防护边坡的抗冲刷能力进行定量研究，采用现场模拟降雨的方法，测量不同雨强降雨时红层软岩生态防护坡面的径流量、坡体截留量和冲蚀量．试验结果表明，在雨强为20mm／h持续降雨190min和雨强为50mm／h持续降雨120min的情况下，采用植被防护的红层软岩边坡基本未冲蚀；生态防护能有效阻碍红层软岩在水环境作用下进一步风化崩解，从而降低红层软岩坡体的冲蚀．

| Abstract: | An in-situ washing-out test was carried out by the artificial simulation of rainfall to quantitatively investigate the anti-washing-out of a red-bed soft rock slope protected by plants. Some parameters, such as runoff amount, rainfall interception and erosion volume, were measured in the conditions of different rainfall intensifies. The results show that a red-bed soft rock slope protected by plants is not washed out nearly when the rain intensity is 20 and 50 mm/h and the duration is 190 and 120 min respectively, and that ecological protections can prevent a red-bed soft rock slope from weathering and disintegrating in a water environment to decrease its washing-out. |
