【摘要】 城市化进程的深入使得城市更新成为重塑空间格局、实现可持续发展目标的必然选择。本研究面向城市更新过程中既有建筑“现状重构评价”“更新优化设计”“施工管理监测”3个阶段的关键问题，研发了既有建筑数字重构与评价、既有建筑更新方案智能优化设计、既有建筑改造智慧管理监测技术，形成了一整套面向城市更新的全过程数字孪生设计、建造与运营管理集成技术链条，推动城市更新的精细化发展，为新时代城市存量更新的数智化转型在技术层面赋能。更多还原

【Abstract】 The deepening urbanisation process has made urban renewal an inevitable choice for reshaping spatial patterns and achieving sustainable development goals.This research addresses key issues in the three stages of existing building urban renewal: "current condition reconstruction evaluation", "renewal optimisation design",and "construction management monitoring".It develops technologies for digital reconstruction and evaluation of existing buildings,intelligent optimisation design for renewal solutions,and smart management monitoring for building retrofits.The study establishes a comprehensive,full-process digital twin technology chain for urban renewal,integrating design,construction,and operational management.This promotes the refined development of urban renewal and empowers the digital-intelligent transformation of urban sto ck renewal in the new era at the technical level.更多还原
