摘　　要：土坯砌体短柱加固选用GFRP格栅和钢丝网两种材料,对3种GFRP格栅及2种钢丝网的8种加固方式进行了轴压试验,发现GFRP格栅和钢丝网加固能够提高试件的抗压强度,格栅加固试件的抗压强度平均值提升12.33%~37.0%,钢丝网加固试件的抗压强度平均值提升29.33%~56.67%,试件的变形能力和整体性也得到了显著改善;GFRP格栅的单双层加固的效果近似,刚度大的钢丝网比刚度小的加固效果要好,GFRP格栅单层加固效果比单层钢丝网要好;所有加固方法中双层钢丝网加固效果最好。The GFRP grating and steel wire mesh are used to strengthen the adobe short column masonry.The axial compression tests are carried out on three GFRP gratings and eight reinforcement schemes of the two steel meshes.It is found that GFRP grid and wire mesh could improve the compressive strength of specimens,and the average compressive strength of specimens strengthened by grid increases by 12.33%-37.0%.The average compressive strength of the steel mesh reinforced specimens increases by 29.33%-56.67%,and the deformation ability and integrity of the specimens are also significantly improved.The reinforcement effect of single and double layers of GFRP grid is similar.The reinforcement effect of steel wire mesh with large stiffness is better than that of steel wire mesh with small stiffness.The reinforcement effect of single layer of GFRP grid is better than that of single layer of steel wire mesh.Among all reinforcement methods,double-layer wire mesh has the best reinforcement effect.
