摘要
结构改造设计与新建工程设计有很大的不同,其自身特点显著,进行改造时需考虑较多方面因素,如不注意极易出现较大问题,严重时会直接影响结构的安全,给工程建设带来极大隐患。论文结合某大型结构改造项目,就实施过程中出现的一些典型问题,阐述了结构改造设计过程中需注意的一些重要事项,并提出相应的预防措施,以期为类似项目的设计起到借鉴作用。
The design of structure transformation and new project design are very different, its remarkable characteristics, consider more factors for the transformation, such as attention prone to large problem, which will directly affect the safety of the structure, bring great unfavorable risk to the project construction. Combined with some typical problems in the implementation process of a large-scale structural renovation project, this paper expounds some important matters needing attention in the process of structural transformation design, and puts forward corresponding preventive measures, so as to provide reference for similar projects.
