摘要
以重庆轨道交通九号线九标区间高架桥梁为例,应用有限元软件Midas-civil对简支梁施工采用双层贝雷梁支架施工方案进行了模拟分析;介绍了双层贝雷梁支架施工工艺及卸荷块卸荷方式。分析结果表明双层贝雷梁支架体系能满足桥梁施工要求;采用卸荷块卸荷能节约成本、加快工期、操作简便,能更好地满足实际的支架卸荷施工。
With the example of Chongqing Rail Transit Line 9,the finite element software Midas-civil is used to simulate and analyze the construction scheme of double-layer Bailey beam support in the construction of simple supported beam.This paper introduces the construction technology and unloading mode of double-layer Beer beam support.The analysis results show that the double layer belay beam support system can meet the requirements of bridge construction,the unloading block can save the cost,speed up the construction period,and the simple operation can better meet the actual support unloading construction.
