摘要/Abstract

摘要： 基于某高层住宅燃气爆炸事故案例，详细介绍爆炸后高层住宅检测评估工作流程及加固处理方法。在检测评估过程中，应按照燃气爆炸事故现场初勘情况，确定检测评估的范围；按照结构构件的破坏特征、裂缝情况、构件变形等对结构构件的受损程度进行判断，为结构后期加固等提供依据。对于结构构件的加固处理，应按照实际损伤程度予以分类，对于已经严重残损的构件应进行相应置换、重新浇筑，对于其余构件则应采取相关加固措施进行补强，以满足结构承载能力及变形要求。

Abstract: Based on a high - rise residential gas explosion accident case, the work flow of detection and reinforcement design of high-rise residential building after explosion was discussed. During detection, the scope of detection shall be determined according to the preliminary investigation of gas explosion accident site. According to the damage characteristics, crack condition and deformation of structural members, the damage degree of structural members is judged, and the basis for the reinforcement of the structure is also provided. For the reinforcement treatment of structural members, it shall be classified according to the actual damage degree. For the members which have been seriously damaged, it shall be replaced and repoured. For the rest members, relevant reinforcement measures also shall be acted, for meeting the bearing capacity and deformation of structure.

Key words: high rise shear wall structure, gas explosion, detection; reinforcement method
