2008年汶川地震是上个世纪最大、最致命的事件之一，无论是在遇难者人数还是地震引发的地质环境危害方面。2008年地震活动的综合影响对当地社会的几个领域造成了重大破坏，包括建筑环境和社会组成部分，突出了在破坏情况下旨在预防和恢复的弹性措施方面存在的巨大差距。因此，必须制定一个多目标和全面的复原力方案，将当地社区的所有不同方面综合起来。在这方面，本文提出了一个广泛的分析和初步的发现，在一个正在进行的项目（REACH）的背景下，在工作线程中进行了结构化的处理。重点是2016年12月在汶川地区进行的实地工作后的建筑环境破坏分析，涉及7个高风险区域的3D激光扫描活动以及相关的审计和初步结构分析。因此，一套外部和内部因素已被确定为可能的调查损害的关键原因。其中，外部因素主要涉及环境和危险属性，而内部指标涉及结构特征和建筑法规。
The 2008 Wenchuan earthquake is one of the largest and deadliest events of the last century, both in terms of victims and seismically-triggered geo-environmental hazards. The combined effects resulting from the seismic activity of 2008 led to major damages in several domains of the local society, including the built environment and the social component, highlighting the extensive gap related to resilience measures aimed at both prevention and recovery in case of a disruption. Thus, it is imperative for the development of a multi-objective and comprehensive formulation for resilience combining holistically all the diverse facets of a local community. To this regard, this paper presents a wide-spectrum analysis and preliminary findings, being structured in working threads specifically addressed in the context of an ongoing project (REACH). The focus is on the built environment damage analysis following the field work which took place in December 2016 in the Wenchuan territory, involving 3D laser scanning activity of 7 high-risk areas and the related audit and preliminary structural analysis of the damage. As a result, a set of external and internal factors have been identified as possible key causes of the surveyed damages. Of these, external factors mainly relate to environmental and hazardous properties, whereas internal indicators involve structural features as well as building regulations.
