摘要:: 现有的抗震避灾韧性评估模型存在着评估精准性差、模型灵活性差的缺陷，为了解决上述问题，提出标致性景观设计抗震避灾韧性评估模型分析与研究。通过对现有模型的分析，对构建的抗震避灾韧性评估模型整体架构进行提出，以此为基础构建整体结构数值分析模型，并采用回归分析方法对非线性动力时程进行分析，得到标致性景观抗震避灾韧性评估指标-损伤指数，采用pushover分析方法对损伤分布系数进行计算，以得到的损伤分布系数为依据建立标致性景观性易损性曲面，由其推导出抗震避灾韧性指数公式，从而实现标致性景观设计抗震避灾韧性的评估。通过实验得到，与现有的抗震避灾韧性评估模型相比较，构建的抗震避灾韧性评估模型极大的提升了评估的精准性与模型的灵活性，充分说明构建的标致性景观设计抗震避灾韧性评估模型具备更好的评估性能。

Abstract:: The present resilience evaluation models of earthquake resistance and disaster avoidance have the defects of low evaluation accuracy and poor model flexibility. In order to solve the problems mentioned above，a model for evaluating the resilience of iconic landscape design is proposed. Based on the analysis of the existing models，the overall framework of the resilience evaluation model for earthquake resistance and disaster avoidance is put forward，and based on which the numerical analysis model of the whole structure is constructed，and the nonlinear dynamic time history is analyzed by regression analysis method. On this basis，the numerical analysis model of the whole structure is constructed，and the non-linear dynamic time history is analyzed by regression analysis method. The damage index，which is the evaluation index of the resilience of the iconic landscape to earthquake resistance and disaster avoidance，is obtained. By using pushover analysis method，damage distribution coefficient is calculated and based on which the vulnerability surface of the iconic landscape is established，and the formulas of the resilience index for earthquake resistance and disaster avoidance are deduced from the surface，so as to realize the evaluation of the resilience of the iconic landscape design to earthquake resistance and disaster avoidance.
