摘　　要：水泥砂浆面层加固法是砌体结构抗震加固常用的方法之一,但是按照GB 50003—2011《砌体结构设计规范》和JGJ 116—2009《建筑抗震加固技术规程》计算得到的加固后砖墙抗震受剪承载力设计值存在一定差异,某些情况下差异还较大。通过收集相关文献中基于试验数据提出的13个计算公式,并基于这些计算公式对两种规范的计算方法进行适用性分析,给出部分可供工程设计人员参考的一些建议。Strengthening with cement mortar splint is one of the most frequently used methods in the reinforcement of masonry structure. However,the results have a certain difference when using the calculation methods in Code for Design of Strengthening of Masonry Structure（ GB 50702—2011） and Technical Specification for Seismic Strengthening of Buildings（ JGJ 116—2009） to calculate shear capacity of strengthened masonry wall. According to the 13 formulas which were proposed on the basis of experiment results,the suitability of calculation methods in the 2standards were analyzed,then some suggestions were given in this paper.
