摘　　要：本文介绍钢筋网水泥砂浆面层加固砖墙承载力增强系数的计算方法。通过比较《建筑抗震加固技术规程》(JGJ 116—2009)和《砌体结构加固设计规范》(GB 50702—2011)中面层加固后墙片抗震受剪承载力的不同计算方法,分析原砖墙砌筑砂浆强度等级、面层厚度、墙体竖向压应力以及原砖墙厚度等因素对承载力增强系数的影响,同时验证两本规范中不同计算方法的合理性。The calculation methods for the reinforcement coefficient of bearing capacity in the masonry strengthening brick wall with bar-mat and cement mortar are introduced. Based on the comparison of calculation methods for the seismic shear capacity of the strengthened wall between the Technical Speeification for Seismic Strengthening of Buildings and Code for Design of Strengthening Masonry Structures, the factors which inqluence the reinforcement coefficient of bearing capacity are analyzed, such as brick wall＇s cement mortar strength, thickness of the reinforcing layer, vertical compressed stress. And the reasonableness of the two Codes in different approaches calculation are proved.
