加筋路堤的双参数地震破坏模型研究

Double-parameter Seismic Damage Model of Reinforced Embankment

现阶段关于加筋土结构的抗震性能设计以及对震后的加筋土结构损伤程度还没有一个统一的评价标准。为完善加筋土结构的抗震性能设计理论,需要对加筋土结构在振动情况下的变形和能量以及极限滞回耗能进行分析。结合室内模型试验,计算试验模型的破损结果,确定模型理论参数,从而建立加筋路堤的双参数地震破坏模型。对完善加筋路堤的抗震性能设计以及对震后破坏的评价具有一定意义。

At present,there is no unified evaluation standard for seismic performance design of reinforced soil structure and damage degree of reinforced soil structure after earthquake.In order to improve the theory of seismic performance design of reinforced soil structures,the deformation and energy of reinforced soil structures and the ultimate hysteretic energy dissipation were analyzed.Based on the lab model test,the damage results of the model were calculated and the theoretical parameters of the model were.It is of certain significance to perfect the seismic performance design of reinforced embankment and to evaluate the damage after earthquake.
