摘要
对现有地表变形作用机理进行归纳和总结,结合机械自锁原理,设计了一种新型抗变形支座装置。并且建立框架、支座和地基有限元模型,通过有限元模拟地表变形来研究支座装置的抗变形性能。由框架柱脚内力-基础位移变化曲线图,发现一般结构随地表变形增加附加内力值也随之增大,而使用了新型抗变形支座装置的有限元模型几乎没有变形,内力变化也很小。最后得出抗变形支座装置具有保护结构不受地表变形影响的作用。
This paper, summarizes the surface deformation mechanism. Combined with the principle of self-lock research, a kind of new resistance to deformation bearing device is designed. A frame, bearing device and foundation finite element model are created. Finite-element simulates surface deformation in order to study the properties of new anti-deformation device. Based on the graphs of frame column foot force-foundation displacement, it is found that the additional internal force in frame will be growing larger when the ground deformation is increasing, whereas the model with new anti-deformation equipment have hardly any deformation, and the change of internal force is very small. Finally it is concluded that the anti-deformation equipment is effective.
