大空间、复杂结构建筑物平移技术研究与应用

结合具体的建筑物平移工程，研究了滚轴的滚动摩擦系数及弹性恢复力特性，提出了平移过程中一种新的竖向隔振技术，并阐明了该技术的隔振原理，对其隔振效果进行了计算机模拟分析，计算了建筑物在提高刚度前、后的自振周期，确定了实际工程中采用的推拉周期。这些成果为安全、可靠地实施大空间、复杂结构建筑物平移奠定了基础，并已成功地应用于建筑物平移工程。

Research and Application of Building Removal Technologywith Large Space and Complex Structure

Based on a concrete building removal project, the rolling friction coefficient and the elastic resilience behavior of its rollers were investigated. A new technology of vertical isolation vibration used in building removal was proposed. The principle of this technology was stated, and its effect of isolation vibration was analyzed through computer simulation. The natural vibration periods of the removed building before and after its stiffness increment were calculated, and then the period of building removal was determined in the engineering application. These results can be used to safely and reliably remove buildings with large space and complex structure, and have been applied to the building removal project.
