Differential settlement simulation test device and method for fabricated subway station
The invention discloses a differential settlement simulation test device and method for an assembly type subway station, and relates to the technical field of underground engineering model test equipment. The test device comprises a station model unit, an elastic cushion layer unit and a ground surface load unit, wherein the station model unit comprises a first top plate component, a second top plate component, a side wall component, a bottom plate component, a middle column component and a middle plate component. The elastic cushion layer unit comprises a first elastic cushion layer and a second elastic cushion layer; the bottom plate component is placed above the first elastic cushion layer and the second elastic cushion layer; and the surface load unit is placed above the station model unit and is used for applying a load. By simulating the influence of station inclination caused by differential settlement on the assembly type subway station joint and the whole, the problem that an existing test device for simulating differential settlement cannot simulate the deformation characteristics and damage forms of the station joint and the whole caused by corresponding severe working conditions is solved.
本发明公开了一种用于装配式地铁车站的不均匀沉降模拟试验装置及方法，涉及地下工程模型试验设备技术领域。该试验装置包括车站模型单元、弹性垫层单元和地表载荷单元，车站模型单元包括第一顶板构件、第二顶板构件、侧墙构件、底板构件、中柱构件和中板构件。弹性垫层单元包括第一弹性垫层和第二弹性垫层；底板构件放置于第一弹性垫层和第二弹性垫层上方；地表载荷单元放置于车站模型单元上方，用于施加载荷。本发明通过模拟不均匀沉降引起的车站倾斜对装配式地铁车站接头和整体的影响，解决现有模拟不均匀沉降的试验装置不能模拟相应恶劣工况引起的车站接头和整体的变形特征与破坏形式的问题。
