This study focuses on the research on the construction of the safety and resilience of urban lifeline systems. It begins by elucidating the connotations of resilient cities and urban lifelines

reviewing the evolution of relevant theories. Subsequently

it constructs an analytical framework for the safety resilience of urban lifeline systems integrating physical infrastructure

operational management

and intelligent decision-making. Furthermore

it explores the role mechanisms

and evaluation methods of key technologies such as Artificial Intelligence

the Internet of Things

and Digital Twin. Finally

strategies and future prospects for improving the safety resilience of urban lifeline systems are proposed from multiple dimensions

including intelligent sensing

resilience-oriented planning

smart management

and dual-use mechanisms for normal and emergency scenarios. The research aims to provide theoretical references and practical pathways for promoting modern urban governance and building livable

resilient

and smart cities.
