基于水文灾害风险评估的建筑遗产预防性保护措施研究

Research on Preventive Protection Measures of Architectural Heritage based on Risk Assessment of Hydrological Disaster

水文灾害发生频繁且对建筑遗产造成损害较大,进行相应的风险评估十分有必要。文章以致灾因子、孕灾环境、承载体和抗灾力四个指标为准则层建立风险评估模型,分析建筑遗产保护优先级,并应用于实例评估,验证了模型的可行性,最后基于风险评估提出预防性保护措施,为建筑遗产水文灾害风险控制及预防性保护提供参考借鉴。

Hydrological disasters occur frequently and cause great damage to architectural heritage,it is necessary to carry out corresponding risk assessment.This paper establishes a risk assessment model based on the four indexes of disaster factor,disaster pregnant environment,carrier and disaster resistance,analyzes the priority of architectural heritage protection,and verifies the feasibility of the model by applying it to the case assessment.Finally,preventive protection measures are put forward based on risk assessment to provide reference for risk control and preventive protection of architectural heritage hydrological disasters.
