摘要
应用理论分析和数值模拟相结合的方法,探讨了高层建筑拆除中的弯矩逐段解体法的基本原理及其应用。通过分析建筑物构件的内力和弯矩,得到了建筑物解体时构件的运动规律。在此基础上,提出了拆除爆破时计算后排内力必须考虑前排构件的作用的新观点。工程爆破实例证明了本文给出的高层建筑物拆除有关计算方法的正确性和可行性。
Based on theoretical analysis and numerical simulation,the basic principle of bending momen gradually disintegration and its application at engineering blasting are discussed in this paper.A motion law of the disintegrative units is obtained by analyzing the internal force and bending moment of the architectural units.A new viewpoint that the influence by the front row stucture should be considered when estimating the force of a row in demolition is put forward.It is proved through engineering practice that the calculation method for demolishing high buildings is correct and feasible.
