Vibration isolation box type roadbed structure and construction method thereof
The invention discloses a vibration isolation box type roadbed structure and a construction method thereof.The vibration isolation box type roadbed structure comprises a plurality of vibration reduction and isolation structures arranged at equal intervals in the road advancing direction, each vibration reduction and isolation structure comprises a raft, a plurality of bearing assemblies are arranged on the top face of the raft, a plurality of foundation piles are vertically arranged at equal intervals on the bottom face of the raft, and the raft is fixed to the road surface through the foundation piles; the plurality of box type roadbed structures are fixedly connected with the bearing assemblies on the top surfaces of the two raft plates; wherein each box type roadbed structure is a hollow box body, and an expansion joint is arranged between every two adjacent box type roadbed structures. The bearing assembly has large vertical bearing capacity and can bear all loads of an upper structure; meanwhile, the variable horizontal rigidity is achieved, transmission of train vibration to foundation soil can be reduced, ground vibration can be effectively isolated, the earthquake response of an upper structure is obviously reduced, and the safety and stability of train operation are improved.
本发明公开一种隔振箱型路基结构及其施工方法，包括：减隔振结构，减隔振结构沿道路行进方向等间距设置有若干个，减隔振结构包括筏板，筏板顶面设置有若干承载组件，筏板底面竖向等间距设置有若干基桩，筏板通过基桩固定在路面上；箱型路基结构，箱型路基结构设置有若干个，且与两筏板顶面的承载组件固定连接；其中，箱型路基结构为中空箱体，相邻箱型路基结构之间设置有伸缩缝。本发明承载组件具有较大的竖向承载力，能够支承上部结构的所有荷载；同时具有可变的水平刚度，既可以减小列车振动向地基土中传播，又可以把地面震动有效地隔开，明显地降低上部结构的地震反应，提高了列车运行的安全性和稳定性。
