【摘要】：绵阳平阳府君阙是全国重点文物保护单位,在汶川大地震中,平阳府君阙受到了历史上最为严重的损伤,阙体各部分出现了石块间扭曲错位、石块断裂和崩落等破坏情形,其稳定性受到显著影响。采用有限元时程分析法,利用Midas GTS软件建立阙体三维模型,通过输入汶川地震波时程曲线,模拟阙体在汶川地震波作用下的力学响应,并将计算结果与现场观测到的阙体破坏变形情况进行比较,结果表明:数值模拟结果与实际观测情况一致,能够反映阙体的真实破坏情况。
[Abstract]:Mianyang Pingyang Fujun que is the national key cultural relic protection unit. During the Wenchuan earthquake, the Pingyang Fujun que suffered the most serious damage in history, and various parts of the quagmire were distorted and dislocated between stones, and the rock was broken and caved off. Its stability is significantly affected. The finite element time-history analysis method and Midas GTS software are used to set up the three-dimensional model of the building body, and the mechanical response of the building body under the action of Wenchuan earthquake wave is simulated by inputting the time-history curve of Wenchuan earthquake wave. The calculated results are compared with those observed in the field. The results show that the numerical simulation results are consistent with the actual observation results and can reflect the true failure of the que bodies.
