摘　　要：随着城市更新的推进,既有建筑改造项目日益增多。该文以重庆市首例在既有老旧房屋内部开挖下沉式地通道的大田湾市政工程房屋加固工程为例,探讨了既有建筑改造全过程的质量安全控制。该文将既有建筑改造质量安全控制分为三个阶段:检测鉴定阶段的风险预判、加固改造设计阶段的风险评估、加固改造施工阶段的风险管控。通过对原结构进行全面检测,为设计提供依据;通过对加固改造可行性和技术可实施性的静态风险评估,确定加固方案;通过施工过程中的静态和动态风险控制,保障原结构安全。该文还介绍了利用智能监测系统对房屋结构变形进行实时监测的做法。该项目的成功实施为类似工程提供了有益借鉴,对保障既有建筑改造过程中的结构安全具有重要意义。With the advancement of urban renewal,the number of existing building renovation projects is increasing rapidly.Taking the Datianwan Municipal Engineering building reinforcement project in Chongqing,the first case of excavating a sunken underpass within an existing old building,as an example,this paper discusses the quality and safety control throughout the entire process of existing building renovation.The paper divides the quality and safety control of existing building renovation into three stages:risk anticipation in the inspection and identification stage,risk assessment in the reinforcement design stage,and risk management and control in the reinforcement construction stage.Through comprehensive inspection of the original structure,a basis is provided for design;the reinforcement scheme is determined through static risk assessment of the feasibility and technical implementability of reinforcement and renovation;and the safety of the original structure is guaranteed through static and dynamic risk control during construction.The paper also introduces the use of an intelligent monitoring system for real-time monitoring of structural deformation of the building.The successful implementation of this project provides valuable reference for similar projects and is of great significance for ensuring structural safety during the renovation of existing buildings.
