摘　　要：干砌甩浆石砌体结构是福建常见的一种民居形式,其结构整体性很差。钢筋网水泥砂浆面层加固方法是有效提高砌体抗剪性能的方法之一。为研究钢筋网水泥砂浆加固法对石墙抗剪性能的影响效果,对9片干砌甩浆石墙及其加固试件进行压剪试验研究,分析了石砌体在水平荷载作用下的破坏形态和破坏机理。试验结果表明:经钢筋网水泥砂浆面层加固后,石墙的抗剪承载力可提高1至3倍,其延性也得到很大提高。The dry-laid stone masonry structure is one of the common structural forms in Fujian province,which has poor structural integrity.The strengthening method with steel-mesh cement mortar is one of the effective methods to improve the shear capacity of masonry structures.In order to study the strengthening effect of steel-mesh cement mortar on stone walls,the pressure-shear tests on nine specimens of dry-laid stone walls and the strengthened ones were carried out,the failure modes and failure mechanism of the wall under the horizontal load were analyzed.The results show that the stone wall＇s shear strength can increase one to three times,and the ductility is also greatly improved.
