The Engineering Governance System of Natural Disaster

China faces a wide range of natural disasters that pose significant threats，making engineering governance complex and challenging. Addressing the bottlenecks in natural disaster engineering governance，such as fragmented theories，isolated technologies，and decentralized systems，this paper proposes the construction of a “theory-technology-institution” three-in-one natural disaster engineering governance system. The theoretical system focuses on the interaction mechanism between engineering structures/materials and geological bodies/geological environment，the construction of a multi-scale evaluation system for long-term service performance safety theory，and the governance engineering-ecological-social resilience evaluation theory. The technological system focuses on full-life cycle monitoring and diagnostic technologies and intelligent equipment，the construction of digital and intelligent systems and dynamic evaluation technologies for governance effects，as well as high-performance green materials/structures and toughness reinforcement and strengthening technologies. The institutional system aims to upgrade and improve major science and technology plans，overall planning methods and systems for governance，and engineering regulations and technical standards systems. By constructing a three-dimensional closed-loop framework of “theoretical foundation-technological breakthrough-institutional guarantee” for the natural disaster engineering governance system，we will advance construction in stages，strengthen cross-departmental collaboration，integrating funds from multiple sources，and form an innovative chain of “basic research-technology transformation-engineering application-policy feedback”. This will establish a comprehensive and interconnected natural disaster resilience engineering barrier，significantly enhancing the overall level of disaster prevention and mitigation.
