摘要
纤维加筋能显著提高粘性土的抗剪强度，并使之具有裂而不断的特性。介绍了纤维加筋粘性土和素土边坡的离心模型试验成果。试验过程中详细观察并记录了边坡的变形和破坏情况。也介绍了对纤维加筋土边坡的数值计算结果。
Fibre reinforcing not only increases the shear strength of cohesive soil, but also prohibits its development when crack occurs. Centrifugal model tests on cohesive soil slopes were conducted during which the deformation and failure pattern of the slopes were carefully observed. The numerical analysis on the fibre reinforced slopes by equivalent additional stress method was also presented. It may be useful for numerical analysis on other types of reinforced earth. That considers the reinforcing effect as an equivalent additional stress acting on the soil skeleton.
