摘　　要：根据对桥梁外观的调查、规范性文件的查找、相关专家的意见以及相对成熟的理论对桥梁可承受承载力进行推测,但这些方式过度依靠经验和经验性数据,差异性程度较大。通过现场试验也可对桥梁承载力进行精确的测定分析,然而因为费用、实验次数以及可观测的实时性等问题不便于实施。有限元分析技术的出现,通过计算机建模和非线性分析可对桥梁承载力进行性动态型实施预测,结合数据分析,对桥梁进行智能化管理。本文通过案例,使用MIDAS/Civil软件对三角挂篮进行结构分析计算,完善三角挂篮的数据资料,为三角挂篮结构优化设计和应用提供可靠依据。According to the investigation of the bridge appearance,the search of normative documents,the opinions of relevant experts and relatively mature theories,the bearable bearing capacity of the bridge is speculated,but these methods rely too much on experience and empirical data,with a large degree of difference.Through the field test,the bearing capacity of the bridge can also be accurately measured and analyzed.However,because of the cost,the number of experiments and the real-time observability,it is not easy to implement.With the emergence of finite element analysis technology,the bearing capacity of bridges can be predicted dynamically through computer modeling and nonlinear analysis,and the intelligent management of bridges can be carried out by combining data analysis.With the emergence of finite element analysis technology,In this paper,we use MIDAS/Civil software to analyze and calculate the structure of the triangle hanging basket,improve the data of the triangle hanging basket,and provide a reliable basis for the structural optimization design and application of the triangle hanging basket.
