| 摘要: |
| 城市的抗震韧性建设已成为国际社会关注的重要议题。作为城市中最关键的基础设施系统之一,道路交通系统在历次大地震中均遭受严重的损坏甚至丧失功能,极大地阻碍震后应急救援和恢复重建工作的开展,造成巨额的间接损失和深远的社会影响。为此,如何有效评估潜在地震威胁下道路交通系统的抗震韧性水平,并提出科学合理的改进建议,对韧性城市的建设以及人类文明的可持续发展具有重要的理论意义和实用价值。本文首先介绍韧性城市理念的发展历程,以道路交通系统为主要研究对象,阐述抗震韧性的定义和内涵；然后,分别从道路交通系统的震后功能评估方法、抗震韧性评价指标、震后恢复策略和震前加固策略4个方面,系统性地总结现有研究的主要方法与成果,并指出当前研究的局限性；最后,对未来的研究趋势进行展望。 |

| Abstract: |
| The construction of urban seismic resilience has become an important topic of international concern. As one of the most critical infrastructure systems in cities, the road traffic systems have suffered severe damage and even lost their functionality in previous major earthquakes, which greatly hindered the post-earthquake emergency rescue and recovery work, resulting in huge indirect losses and profound social impacts. Therefore, it is of great theoretical significance and practical value for building resilient cities and sustainable development of human civilization to evaluate the seismic resilience of road traffic system under potential earthquake threat and provide scientific and reasonable improvement suggestions. In this paper, the development history of urban resilience is introduced firstly, and the definition and connotation of seismic resilience are expounded, taking road traffic system as the main object. Then, the main methods and achievements of the existing research are systematically summarized in the fields of post-earthquake functionality assessment method, seismic resilience indicator, post-earthquake recovery strategy and pre-earthquake retrofit strategy of road traffic system, and the limitations of current researches are pointed. Finally, the future research trend is discussed. |
