摘　　要：对长江以南低山丘陵区红壤土岸坡抗侵蚀性能开展定量研究具有重要意义。通过边坡模型实验,在人工降雨条件下对红壤土土工格室护岸进行了不同坡度、不同降雨强度及不同格室类型的降雨冲刷试验,对不同格室的抗侵蚀性能进行了定量分析。结果表明:在该试验降雨条件下,土工格室抗侵蚀性良好,对红壤土边坡的降雨冲刷防护效果明显,可在工程实践中推广应用。The study on erosion resistance performance of the red loam bank slope at hilly area distributed in the south of Yangtze River has great significance. Through the experiment of slope model performed under the condition of artificial rainfall, the geocell - protected red loam slope underwent a series of rainfall erosion tests with various slope grades, different rainfall intensities and different geocell types. The erosion resistance performance of geocell slope protection was also analyzed qualitatively. The results showed that under the condition of artificial rainfall, geocell reveals good resistance to erosion while its effect of rainfall erosion protection on red loam slope is obvious, which could be widely applied in engineering practice.
