Multi-dimensional Resilience Framework Development for Culvert Infrastructure Systems

在2019年加拿大基础设施报告卡中，我们的基础设施状况处于危险之中，这应该引起所有加拿大人的关注，加拿大的公共基础设施在未来几十年将需要大量关注。涵洞是公路资产的重要组成部分，需要进行例行检查、维护和及时维修和更新。然而，前所未有的自然灾害，如地震，洪水，山体滑坡，以及这些资产的广泛地理空间分布，加上严格的预算限制，给运输机构带来了巨大的挑战。因此，涵洞抵御自然灾害的脆弱性和复原力评估对于实现可持续和有复原力的交通网络至关重要。本研究的长期目标是评估涵洞在洪水灾害中的脆弱性和恢复力，以提高涵洞管理方法。这项研究的结果有望显着提高我们的理解和管理涵洞基础设施的自然灾害或不必要的中断。这一合作计划将产生新的见解，促进涵洞和运输弹性分析的改进，并优化资源分配。

In the Canadian Infrastructure report card 2019, it is demonstrated that the state of our infrastructure is at risk, which should be cause for concern for all Canadians and Canada's public infrastructure will require significant attention in the coming decades. Culverts comprise a crucial segment of highway assets that require routine inspections, maintenance, and timely repair and renewal. However, unprecedented natural hazards like earthquake, floods, landslides, and wide geospatial distribution of these assets accompanied by strict budget restrictions pose substantial challenges for the transportation agencies. Therefore, the vulnerability and resilience assessment of culverts against natural hazards is essential to achieve a sustainable and resilient transportation network. The long-term objective of this research is to assess the vulnerability and resilience of culverts against flood hazards for upgrading the culvert management practices. The outcome of this research is poised to significantly improve our understanding and management of culvert infrastructure from natural disasters or unwanted disruptions. This collaborative program will produce new insights prompting the improvement of culvert and transportation resilience analysis with optimal resource allocation.
