Subway station anti-collision bearing column with negative Poisson's ratio lattice structure and operation method of subway station anti-collision bearing column
The invention relates to a subway station anti-collision bearing column with a negative Poisson's ratio lattice structure and an operation method of the subway station anti-collision bearing column, and belongs to the field of new materials and new structures for subway supporting. The structure mainly comprises an outer-layer panel, an inner-layer panel, a core, core concrete, a dot matrix interlayer and a unit cell structure. An anti-collision outer layer energy absorption structure is designed on the basis of a traditional bearing column and used for metro bearing, the energy absorption effect is improved, and the harm that a metro is out of control is greatly reduced. When the bearing column is impacted, the dot matrix interlayer can generate a certain amount of deformation at the moment of contact impact to buffer instant impact force, in the structural deformation process, after internal structures extrude each other, the buffer structure is folded, the relative density of a high-stress part is continuously increased, and the strength of the buffer structure is gradually improved; the effects of dynamic buffering and step-by-step impact force counteracting are achieved, and the problems that the buffering structure is damaged by instant impact, and the follow-up bearing capacity is reduced can be effectively solved.
本发明涉及一种具有负泊松比点阵结构的地铁站防撞承重柱及其运行方法，属于地铁支撑用新材料和新结构领域。主要包括：外层面板、内层面板、芯子、核心混凝土、点阵夹层、单胞结构。本发明在传统承重柱的基础上设计一个防撞外层吸能结构，用于地铁承重，增加吸能效果，使地铁失控的危害大大降低。当承重柱受到撞击时，点阵夹层在接触冲击的瞬间能够产生一定量形变以缓冲瞬间冲击力，结构变形过程中，内部结构相互挤压后使缓冲结构收拢，高应力部位的相对密度不断增加，缓冲结构强度逐渐提高，实现动态缓冲、逐级抵消冲击力的效果，能够有效避免缓冲结构瞬间冲击破坏以及后续承载力下降等问题。
