结合西岳庙—天威咫尺石牌坊加固工程实例,利用CFRP加固技术对石质矩形梁进行了受弯试验,对比分析了加固前后石梁的破坏形态、承载力以及跨中挠度,指出CFRP加固石质文物后,其破坏形态由正截面脆性破坏转化为斜截面延性破坏,其剩余承载力和变形能力得到了显著提高。
Combined with the example of strengthening the Xifanyi Temple - Tianwei Zhiliao stone arch bridge, the CFRP reinforcement technology was used to test the bending behavior of the stone rectangular beam. The damage form, bearing capacity and midspan deflection of the stone beam before and after reinforcement were analyzed. After the cultural relics, the failure mode is changed from the normal brittle failure to the oblique ductile failure, and the residual capacity and deformation capacity are significantly improved.
