摘要
采用理论分析与数值计算的方法对高耸建筑物爆破拆除中建筑物倾倒过程中的内力进行了分析计算 ,得到了内力的演化规律。同时提出了建筑物倾倒过程中发生断裂的判据 。
In this paper, by the means of theory and numerical simulation, the change of inner stress of high building during its collapse by blasting is calculated. A criterion of fracture is proposed. At the same time, the reason and position of fracture is determined . Simulation shows that fracture position isn't at the biggest M or the biggest Q which other documents told. Owing to the influence of axial stress, the fracture position moves upward.
