【摘要】：綿陽平陽府君闕是全國重點(diǎn)文物保護(hù)單位,在汶川大地震中,平陽府君闕受到了歷史上最為嚴(yán)重的損傷,闕體各部分出現(xiàn)了石塊間扭曲錯(cuò)位、石塊斷裂和崩落等破壞情形,其穩(wěn)定性受到顯著影響。采用有限元時(shí)程分析法,利用Midas GTS軟件建立闕體三維模型,通過輸入汶川地震波時(shí)程曲線,模擬闕體在汶川地震波作用下的力學(xué)響應(yīng),并將計(jì)算結(jié)果與現(xiàn)場觀測到的闕體破壞變形情況進(jìn)行比較,結(jié)果表明:數(shù)值模擬結(jié)果與實(shí)際觀測情況一致,能夠反映闕體的真實(shí)破壞情況。
[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.
