摘　　要：为有效指导连续梁桥合拢阶段的施工与监控,分析了临时固结及体系转换的原理和模拟方式,并结合有限元程序midas/civil,研究4种不同的模拟方法在midas/civil程序中的实现过程.结果表明,临时固结的刚度及下部结构的刚度是体系转化模拟的关键,在模拟体系转化的过程中,应结合施工的实际情况来考虑临时固结及下部结构的刚度对体系转化的影响.In order to give efficient directs to the construction and supervisory control of continuous beam bridge in the process of closure, we analyzed the principle and simulation methods of the temporary consolidation and system conversion, and illustrated how the four different simulation methods were realized in the finite element program MIDAS / Civil. The results show that the rigidity of temporary consolidation and infrastructure is the key points to the simulation system conversion, and the effect of the rigidity of temporary consolidation and infra- structure to the system conversion should be took into consideration according to actual situation of construction in the process of simulating system conversion.
