摘要

依据加筋理论，假定加筋路堤边坡的破裂面为对数螺旋面，运用极限分析的上限原理推导加筋路堤临界高度的上限解。在不计加筋力时，该解与无筋路堤的临界高度一致。结合算例，得出加筋能提高路堤临界高度的结论。

Abstract

Based on the theory of reinforcement and assuming the fracture surface of reinforced embankments is a log-spiral failure surface

the limit analysis method is used to deduce the critical height of reinforced embankments. The solution is consistent with the critical height of unreinforced embankments when the force is not consider. It is concluded that the critical height can be improved through reinforcing embankments.
