Sea level rise (SLR) poses increasing flood risks to coastal cities and infrastructure. We propose a general framework of engineering resilience for infrastructure systems in the context of climate change and illustrate its application for the assessment of SLR impacts on the rail rapid transit network in Boston. Within this framework, projected coastal flood events are treated as exogenous exposure events, which interact with both physical and topological endogenous network characteristics. We consider contextual aspects of resilience by assigning relative importance to links based on passenger flows. Resilience is computed assuming a linear recovery model, neglecting recovery strategies. Using a reference 1–100 year coastal flood event we show decreasing resilience of the rail transit network as projected SLR increases. The proposed framework can be readily extended to consider more sophisticated performance models, recovery strategies, other perturbation events, and additional contextual factors, such as equity considerations.

海平面上升 (SLR) 给沿海城市和基础设施带来越来越大的洪水风险。我们提出了气候变化背景下基础设施系统工程弹性的一般框架，并说明了其在评估 SLR 对波士顿快速轨道交通网络的影响方面的应用。在这个框架内，预测的沿海洪水事件被视为外源性暴露事件，它与物理和拓扑内源网络特征相互作用。我们通过为基于客流的链接分配相对重要性来考虑弹性的上下文方面。弹性计算假设线性恢复模型，忽略恢复策略。使用参考 1-100 年的沿海洪水事件，我们表明随着预计 SLR 的增加，轨道交通网络的弹性降低。
