摘要
为研究夯土民居裂缝注浆修补技术的加固效果,采用两个基本一致的足尺1:1夯土结构模型进行模拟地震振动台试验。对两模型在各烈度地震下的地震反应进行对比,试验得出加固模型的开裂表现、加速度反应及层间位移角等均显著改善。验证了裂缝注浆修补技术对夯土结构加固的可行性,为夯土民居的加固改造提供参考和建议。
In order to study the reinforcement effect of grouting repair technology for bauxite cracks,two identical full-scale 1∶1 bauxite structure models are applied to simulate seismic shaking table test.The seismic responses of the two models under various seismic earthquakes are compared.The results show that the cracking performance,acceleration response and interlayer displacement angle of the reinforcement model are significantly improved,and the feasibility of crack grouting repair technology for the reinforcement of bauxite structure is verified,and it provides the reference and suggestion for the reinforcement and reconstruction of bauxite dwellings.
