［摘要］鋼筋網(wǎng)-水泥砂漿面層加固砌體墻是加固砌體結(jié)構(gòu)的常用方法，現(xiàn)階段人們對(duì)該加固方法的關(guān)注點(diǎn)較多集中在加固前后墻體的抗震性能方面，較少關(guān)注加固后面層的耐久性問(wèn)題，如面層開(kāi)裂、鋼筋銹蝕以及由此所帶來(lái)加固效果的弱化等。以某已加固砌體結(jié)構(gòu)住宅實(shí)例和實(shí)驗(yàn)室磚墻加固試件為例，介紹了鋼筋網(wǎng)-水泥砂漿面層加固砌體墻存在的面層開(kāi)裂情況，分析了面層開(kāi)裂原因，并在構(gòu)造措施方面提出了相應(yīng)的建議，以期為該加固方法的工程應(yīng)用及相關(guān)規(guī)程的修訂提供參考。

Abstract: Structure member strengthening with steel reinforcement web-cement mortar splint is a common method to strengthen the masonry structure. Current concerns about the strengthening method focus on the seismic performance of the wall before and after strengthening, and paid no attention to the layer durability problems of the wall after strengthening, such as the surface layer crack, steel corrosion and so on, which can weaken the reinforcement effecting. A masonry structure and test specimens of masonry wall were selected as examples, the problem about cement mortar surface layer crack was introduced, and the crack reason was analyzed. The improvement suggestions in the construction measures aspect were proposed which can provide reference for the strengthening engineering and for the further revision of the standard.

Keywords: strengthening with steel reinforcement web-cement mortar splint; masonry structure; crack; design suggestion
