摘　　要：文章基于混合相似理论进行了复杂载荷作用下的连接器基座加强区结构模型设计,完成了极限承载能力模型试验,并通过模型试验结果与数值仿真结果的对比,验证了数值仿真方法的正确性。通过文中的研究建立了超大型浮体连接器基座加强区结构模型试验技术、得到连接器基座加强区结构的极限压缩载荷,对多轴载荷作用下的结构物极限强度研究和推进具有重要意义。The test model is designed in accordance with distorted similarity theory,and the ultimate strength test is carried out.Model and nonlinear finite element analyses are combined together to study its progres鄄sive collapse behavior under combined vertical and longitudinal loads.By comparing the model test results with the numerical simulation results,the correctness of the numerical simulation method is verified.This structure model test technology is first established to obtain the ultimate compressive load of the connector foundation support reinforcing area structure under complex loads,which is of great importance to the study and promotion of the ultimate strength of structures under complex loads.
