摘要

假定破裂面为一过坡脚的斜平面，分别以传统塑性理论和广义塑性理论为基础，导出了加筋土坡临界高度的计算公式。通过与前人试验结果的比较发现，虽然基于广义塑性理论极限法求得的加筋土坡临界高度值要比基于传统塑性理论极限法求得的临界高度值略偏大，且更接近于试验实测值，但二者在工程中均是可靠的，都可用于加筋土坡设计时的参考。

Abstract

Assuming that the failure surface to be an inclined plane through the slope toe

and based on the classical plasticity theory and the generalized plasticity theory respectively

the computation formulas of the reinforced slope’s critical height are deduced. Comparing to the previous experimental values of the reinforced slopes

although the critical height with the generalized plasticity theory limit analysis method is slightly higher than the critical height with the classical plasticity theory limit analysis method

and it is more close to the experimental values; both of them are reliable in the engineering; and they can be used as reference for reinforced slope design .
