Pile group foundation bearing platform for resisting horizontal earthquake
The pile group foundation bearing platform for resisting the horizontal earthquake comprises a bearing platform body and an energy consumption device, and the energy consumption device comprises an energy consumption mechanism, a vibration power source mechanism and a cable; the energy consumption mechanism is connected with the vibration power supply mechanism through a cable; current provided by the vibration power supply mechanism is increased along with the increase of the vibration amplitude of the bearing platform; the energy consumption mechanism comprises two energy consumption assemblies which are overlapped up and down, each energy consumption assembly comprises a shell, an elastic piece, a mass block, a magnet exciting coil and magnetorheological fluid, and the mass block is provided with a damping through hole for the magnetorheological fluid to penetrate through. In the application, when the vibration power supply mechanism can correspondingly and dynamically adjust the magnitude of the current in the excitation coil according to the intensity of the earthquake action actually borne by the bearing platform, the damping coefficient of the movement of the magnetorheological fluid is dynamically changed, so that the damping coefficient in the energy consumption assembly is matched with the intensity of the actual horizontal earthquake action; therefore, good vibration reduction and energy consumption effects are achieved.
本申请涉及一种用于抵抗水平地震的群桩基础承台，其包括承台主体和耗能装置，耗能装置包括耗能机构、振动电源机构和线缆；耗能机构与振动电源机构通过线缆连接,振动电源机构提供的电流随着承台振动幅度增大而增大；耗能机构包括两个上下叠合的耗能组件，耗能组件包括外壳、弹性件、质量块、励磁线圈和磁流变液，量块开设有供磁流变液穿设的阻尼通孔。在本申请中，当振动电源机构可以根据承台实际受到的地震作用强度，相对应地动态地调节励磁线圈中电流的大小，来动态改变磁流变液移动的阻尼系数，使得耗能组件中的阻尼系数与实际的水平地震作用强度相适配，以起到很好的减振耗能效果。
