The idea of resilient city has become influential in the urban study area as the concept of resilience is gradually implicated in the urban design method. Infrastructure, the material basis of the urban environment, decides whether citizens can safely transfer and rescue can be carried out when the disaster happens, which has a strong relation to the resilience. There is limited research material on the theme, “infrastructural resilience”, but there are precedent study cases on infrastructures, which encompassed the idea of resilience. What we need to do is extract key information concerning the correlative research by effective means, thereby providing clues for further research on the resilience of infrastructures. Using mixed methods, including direct retrieval, feature iteration of retrieval and data iteration of retrieval to extend the search scope of literature, as well as scientific mapping method to explore the current research focus, weak point, and future trends of the infrastructural resilience research, this paper aims to form a more comprehensive understanding in the infrastructural resilience study. The existing research mainly focuses on risk, including risk types, risk assessment and risk management; studies on robustness, recovery, optimization measures and effectiveness evaluation of foundation toughness are relatively weak. And these themes above have great potentials in future research.
