High-damping-performance railway station building foundation structure and construction method
The invention discloses a railway station building foundation structure with high damping performance and a construction method, the foundation structure comprises a bottom plate layer, connecting piles and pile foundations for supporting the connecting piles, and the bottoms of the pile foundations are connected with a plurality of steel bars; a rail and a ceiling are arranged above the bottom plate layer, the bottom plate layer comprises a main body connecting side and a rail side, a separation groove is formed between the main body connecting side and the rail side, and a shock absorber and a shock pad which are used for shock absorption and energy absorption are arranged in the separation groove. According to the station building foundation structure, the bottom plate layer provided with the rail is separated from the bottom plate layer on the main body connecting side, vibration is prevented from being transmitted to the main body connecting side from the rail side through the vibration absorbers and the damping pads at the separation positions, vibration on a building main body structure is reduced, and then the lower portion of the bottom plate layer is connected with the connecting piles and the pile foundations, so that the connecting effect is good. The pile foundation is buried underground, the distance between the pile foundation and the ground is not smaller than 8 m, when vibration generated when a train passes through is transmitted to the underground and then transmitted to the main body structure of the station building, the distance is long, and the good damping effect can be achieved.
本发明公开了一种高减震性的铁路站房基础结构及施工方法，该基础结构包括：底板层、连接桩以及支撑连接桩的桩基，桩基的底部连接有多根钢筋；底板层的上方设有轨道与顶棚，底板层包括主体连接侧与铁轨侧，主体连接侧与铁轨侧之间设有分隔槽，分隔槽内设有用于减震吸能的减震器与减震垫。本发明的站房基础结构通过将设有轨道的底板层与主体连接侧的底板层分隔开，并在分隔处通过减振器和减震垫，阻断了震动从轨道侧传递至主体连接侧，减少了对建筑主体结构的震动，其次，底板层下方连接有连接桩、桩基，桩基埋设于地底，与地面的距离不小于8米，当列车经过产生的震动传递至地底，再次传递至站房的主体结构时距离较远，可以起到很好的减震效果。
