在對鋼管混凝土構件極限承載力的分析計算中，本文提出了核心混凝土的三維非線性應力?應變全量和增量本構關系模型，採用完全的拉格朗日表述來考慮與變形歷史有關的大變形問題，並對長細比、含鋼率和偏心率在較大范圍內變化的方、圓鋼管混凝土構件的非線性屈曲承載力分別進行了試驗和理論對比分析研究，結果表明二者符合較好。Through analysis and compare, the measure fitting for huxi bank was put forward. ( 3 ) introduced fast lagrangian analysis of continua. flac3d is a three - dimensional explicit finite - difference program. it can simulate the behavior of three - dimensional structures built or soil, rock or other material and can simulate plastic collapse, flow and large - strain accurately
（ 3 ）對三維快速拉格郎日有限差分法進行了介紹，三維快速拉格朗日法是一種基於三維顯式有限差分法的數值分析方法，它可以模擬巖石或土體及其它材料的三維力學行為，可以準確模擬材料的屈服、塑性流動、軟化直至大變形，尤其在材料的彈塑性分析、大變形分析以及模擬施工過程等領域有其獨到的優點。
