摘要
加筋土边坡在实际工程中有重要的应用,对该类边坡的稳定性分析是非常重要的工作。然而对二级加筋边坡稳定性研究较少。利用上限法,对二级加筋边坡的稳定性进行了研究。建立了外力功率,土体与筋材能量耗散方程,并利用Matlab优化平台对临界高度进行求解。所得结果可以指导边坡失稳分析与防护设计。与已有结果的对比分析表明:采用本文方法对二级加筋土坡的稳定性分析是简单有效的。
Reinforcement soil slope is applied widely in practice engineering,of which stability analysis is very important.However,the research of two-steps reinforcement soil slope is less.The two-steps reinforcement soil slope stability is studied by the limit analysis upper bound theorem.The external work rate and the internal energy dissipation rate is calculated,and the critical height is solved with Matlab.The stability of slope with multi-steps is analyzed to provide a theoretical basis for studying the causes of instability and the reinforcement design.By comparison between calculated result and existing result,this method is effective to the stability of slope with two-step reinforcement soil slope.
