摘要

本文的目的是利用全局数值动力学方法分析黎巴嫩地震荷载作用下的边坡稳定性。这种方法可以考虑简化工程方法中通常忽略的重要参数，如土壤变形能力和地震输入的频率含量。这些参数在地震荷载下触发失稳是至关重要的。利用弹塑性土体特性进行分析，可以监测地震后边坡状态的演变，并明确最可能的破坏圈。本文将重点讨论边坡的加固问题，以便为地震荷载作用下的脆弱边坡提供最合适的加固方案。

Non linear global dynamic analysis of reinforced slopes stability under seismic loading

The aim of this work is to analyze the slopes stability under seismic loading in Lebanon using a global numerical dynamic approach. This approach allows taking into account important parameters that are generally ignored in simplified engineering methods as the soil deformability and frequency content of seismic input. Such parameters are critical in triggering instability under seismic loading. Analysis is conducted using elastoplastic soil behavior that could monitor the evolution of the slope state after an earthquake and clarify the most probable failure circles. It will focus on the slopes reinforcement in order to give recommendations for the most appropriate reinforcement scheme for vulnerable slopes under seismic loading.
