摘　　要：分析了加固规范(CECS25∶90)中预应力撑杆构造形式的缺陷,提出采用槽型缺口取代规范中建议的三角形缺口,并对其焊接构造提出规定,以提高加固的有效预应力,且提出了实际的加固施工步骤。通过试验研究,验证了该改进方案的可行性和易操作性。Analyzed to the structural form's blemish of the pre-stressed struts inside the reinforced code(CECS 25∶90),and bring up to adopt the slot type indentation to replace the triangle indentation that the code suggests;as to improve the validity of the pre-stress,the provision to it's weld forms has been suggested;and the physically reinforced steps have been brought up.At the end,based on experiment research,this improved project's possibility with easy operability has been verified.
