传统的以弹性理论和经验方法为基础的路面结构设计方法,对路面结构的安全性评价存在着不合理性。安定理论可为复杂荷载作用下的路面结构承载力分析提供理论依据,基于该定理发展了一种应用于路面结构的安定分析方法,并应用于2层路面结构的安定分析,计算给出了荷载作用方式、路面结构形式、材料性质变化对路面安定极限影响的定量分析结果,通过对比表明了安定分析应用于路面结构的可行性。安定极限可为路面结构的分析与设计提供一定的参考价值。
The traditional design method of pavement structure based on elastic theory and experience method is not reasonable to evaluate the safety of pavement structure. The stability theory can provide a theoretical basis for the analysis of the bearing capacity of pavement under complex loads. Based on the theorem, a stability analysis method applied to pavement structure is developed and applied to the stability analysis of pavement structure of two floors. The mode of action, the pavement structure and the qualitative analysis of the influence of material property on the stability of pavement, the feasibility of applying stability analysis to the pavement structure is demonstrated through comparison. The stability limit can provide certain reference value for pavement structure analysis and design.
