摘　　要：高性能水泥复合砂浆钢筋网薄层(HPFL)窄条带加固技术具有造价低廉、施工简易、工作可靠等诸多优点。介绍了HPFL窄条带抗震加固砌体结构的研究成果:HPFL窄条带能显著提高墙体的抗震抗剪承载力、抗侧刚度、耗能能力和延性,并减缓墙体刚度退化的速度。结合工程实例,给出了具体设计和施工方法。经计算,加固前部分墙肢抗震承载力不满足要求,加固后各楼层墙肢均满足抗震承载力要求。High performance ferrocement laminate（HPFL） banding strengthening technique has many advantages,such as low cost,simple construction and reliable operation.The authors introduce some masonry seismic strengthening research achievements using HPFL banding,such as it can improve the seismic shear strength,lateral stiffness,energy dissipation capacity and ductility of the wall,it also can slow down the speed of the stiffness degeneration.Combining with a project example,the specific design and construction method are given out.It is testified by calculating that partial walls did not meet the seismic capacity requirements before strengthening,however all the walls match the standards after strengthening.
