[提要]  介绍了8片低强度砂浆砖砌体经钢筋网砂浆抹面加固后的抗侧力对比试验，其中面层厚度、加固面数和竖向压力作为变化参数。试验表明，钢筋网水泥砂浆抹面加固低强度砖砌体可以显著提高墙体的水平承载能力和抗侧移刚度。总结了加固参数对加固效果的影响，提出了适用于此类墙体加固的抗侧力建议公式。

The contrast experiment of eight brick masonry walls with low strength mortar strengthened with steel-meshed cement mortar is introduced. Walls are different from each other because the parameters, such as thickness of cement mortar, side number of cement mortar and vertical load, are not exactly the same. The experiment result shows the strengthening method can notably improve horizontal ultimate load and the lateral stiffness of the walls. The effects of the strengthening are summarized and some practical formulas are concluded in order to solve the similar problems.
