提出了土工合成材料加筋土结构的抗震设计方法。这些程序基于拟静力极限平衡分析，该分析考虑水平加速度并包含永久位移限制。考虑到不同的破坏模式，进行了内部和外部稳定性分析，以确定土工合成材料所需的强度和长度。参数研究表明，地震加速度对不同坡角和不同土性的加筋土结构设计的影响。对于小地震加速度下的垂直斜坡，连接/复合破坏决定了所需的土工合成长度。抵抗直接滑动所需的长度随着地震加速度的增加而迅速增加。在适度的设计加速度下，该长度可能变得不切实际。针对这种情况，提出了一种基于容限抗滑移量的设计方法。将所建议的程序与...
Seismic design procedures are proposed for geosynthetic-reinforced soil structures. The procedures are based on a pseudo-static limit equilibrium analysis, which considers horizontal acceleration and incorporates a permanent displacement limit. Internal and external stability analyses are conducted to determine the required strength and length of geosynthetic, considering different modes of failure. Parametric studies illustrate the effects of seismic acceleration on the design of reinforced soil structures having different slope angles and soil properties. For vertical slopes at small seismic acceleration, tieback/compound failure dictates the required geosynthetic length. The length required to resist direct sliding increases rapidly as the seismic acceleration increases. This length may become impractical at moderate design accelerations. For such cases, an alternative approach based on a tolerable displacement against direct sliding is proposed for design. The proposed procedures are compared with the...
