以某连续梁桥悬臂拆除工程为背景,对主墩进行了拆除过程有限元仿真计算分析,并在主墩关键位置布置应变计进行施工监测,以确保拆除过程桥墩的结构安全,使拆除工作的全过程处于受控状态。%Taking some cantilevel demolishment of main piers with continuous beam bridge as the background,the paper undertakes the finite element simulation calculation and analysis of the demolishment process of the main piers,and undertakes the construction supervision over the key parts of the main piers with the strain gauge,so as to ensure the structural safety of the piers in the demolishing process and keep the whole process of demolishment within the control.
