摘要
依托于横江梅林大型水利枢纽工程,利用有限元通用软件Abaqus,建立岩石地基+中墩结构+帆的FEM模型,同时采用Tie理论模拟了帆与中墩结构两者之间的受力关系,根据4种不同设计工况,计算得到整个模型的应力及位移结果,分析整个模型的受力状态及变形规律;提出结构应力较大的部位需加强配筋的建议,FEM仿真分析的结果能够为此类复杂结构的设计及配筋方案提供技术支撑和经验参考。
Based on the large-scale Meilin water conservancy project of Hengjiang,using the general finite element software Abaqus,the FEM model of rock foundation+middle pier structure+sail was established.Meanwhile,the stress relationship between sail and middle pier structure was simulated by Tie theory.According to the four different design conditions,the stress and displacement results of the whole model were calculated,and the stress state and deformation law of the whole model were analyzed.It's suggested that the parts with large structural stress need to be reinforced,and the FEM simulation analysis results could provide scientific technical support and experience reference for the design and reinforcement scheme of such kind of complex structure.
