基于复合加筋机理的加筋边坡稳定性上限解

在加筋边坡的稳定性解析解中，鉴于加筋机理的复杂性，提出了同时考虑摩擦加筋和准黏聚力加筋机理共同作用的复合加筋理论。为验证该理论的合理性，通过与已有临界高度试验结果对比，得出该理论结果比基于常用加筋机理得到更接近于实测值，验证了该理论有效性和适用性。基于极限分析上限法，假定破裂面为对数螺线面，建立了基于复合加筋机理的加筋边坡抗震稳定性分析上限解模型。应用该计算模型，不仅可以合理计算出由复合加筋机理所得到的边坡稳定性，而且还可分别简化为准黏聚力或摩擦加筋机理的结果。通过对典型算例的计算，探讨了常用加筋机理与复合加筋机理对抗震稳定性的影响，结果表明：考虑复合加筋机理作用所需的极限加筋力将会降低。

Upper Bound Method for Stability of Reinforced Slope Based on Composite Reinforcement Mechanism

This paper presents a composite reinforcement mechanism for reinforced structures.The principal of quasi-cohesion and friction-bar theory are both introduced.In order to evaluate the validity of the proposed theory,the previous experimental results are adopted to compare.It is found that the result obtained by the composite reinforcement mechanism is slightly higher than that of simplex reinforced theory,and it is more close to the experimental values.It is proved that the proposed method is more efficient ...
