摘　　要：对广州某连续刚构桥两套切割方案进行对比,分析初始切割线和切割方法对拆除过程和桥梁保留部分的影响。从梁体承载力、桥墩承载力及梁端的变形三方面进行分析,确定最佳的初始切割线。对两种切割方法中桥墩的受力进行对比分析,选择对称切割法进行切割。By comparing two sets of cutting programs in a continuous rigid frame bridge in Guangzhou, the paper analyzes the initial cutting line and the influence of cutting method to demolish process and the re- main part. From three aspects analysis of bearing capacity of the beam,bearing capacity of the pier and de- formation of the beam end,it determines the optimized initial cutting line. The forces of two piers cutting programs are analyzed, and the symmetrical cutting method for cutting is selected.
