摘　　要：结构有限元模拟在桥梁的结构分析中有很重要的作用。对在役桥梁进行检测和加固,需要进行静载试验。静载加载时有不同的加载工况。文章通过对某钢筋混凝土连续刚构桥在某偏载加载工况下的裂缝模拟,确定有限元模型的可靠性,并为后续桥梁结构分析提供一定的理论依据。Structure finite element simulation plays an important role in the structure analysis of bridge.To detect and reinforce the bridge in service,static load test should be done.There are different loading conditions under static load.The reliability of the finite element model is determined by the fracture simulation of a reinforced concrete continuous rigid frame bridge under partial load condition,and the theoretical basis is provided fo r the subsequent structural analysis of the bridge.
