不同加筋方式对风积沙路堤稳定性的影响分析

以风积沙路堤边坡为研究对象，对风积沙填料填筑的路堤边坡，从不同加筋方式进行了数值模拟研究。结果表明:等长加筋方式存在一定不足，采用不等长加筋方式较为合理。不等长布筋方式中，集中布筋方式长筋和短筋的轴力分布更加均衡，但从边坡变形和稳定性考虑，间隔布筋方式更合理。不等长加筋存在一个最佳长度比，推荐不等长加筋的长度比为1∶1.6。

Influence of Different Reinforcement Methods on Stability of Aeolian Sand Embankment

Taking Aeolian sand embankment slope as the research object, the embankment slope filled with aeolian sand was numerically studied from the perspective of different reinforcement methods. The results show that there is a certain shortage in the way of equal length reinforcement, and it is more reasonable to adopt the way of unequal reinforcement. In the case of unequal length reinforcement, the axial force distribution of long reinforcement and short reinforcement in a centralized reinforcement method is more balanced. However, considering the deformation and stability of the slope, the spacing reinforcement method is more reasonable. There is an optimal length ratio for the unequal reinforcement, and the length ratio of the recommended unequal length is 1:1.6. These results can provide a reference for the construction and design of similar areas.
