对两种不同密度粘性土的素土和纤维加筋土直立边坡进行了离心模型试验研究，并用毕晓普法进行了稳定分析，所观测到的边坡破坏形式、破坏过程以及稳定分析计算结果对推广这种加筋形式，认识相关工程问题是很有意义的。 Centrifugal model tests were performed on the upright slopes of plain soil and fiber reinforced soil with two different densities of soils. The stability analysis was performed using Bishop’s method. The observed failure modes, failure processes, and stability analysis results were observed. To promote this kind of reinforcement, it is of great significance to understand related engineering issues.
