Anti-seismic structure and method for improving anti-seismic performance of building pile foundation in soft soil foundation
The invention discloses an anti-seismic structure and method for improving the anti-seismic performance of a building pile foundation in a soft soil foundation, and belongs to the technical field of building pile foundations. According to the construction method, protection of the building pile foundations is mainly achieved in the mode that shallow protection piles are arranged, and the shallow protection piles are arranged on the peripheries of the building pile foundations and/or arranged between the building pile foundations below a bearing platform, and the shallow protection piles are arranged on the peripheries of the building pile foundations and between the building pile foundations or arranged below the bearing platform in various arrangement modes; the vertical bearing capacity of the whole building pile foundation can be improved, the shallow protection pile can share the soil dynamic load borne by the building pile foundation in the earthquake process, fluctuation energy in the earthquake process can be consumed by sacrificing the shallow protection pile itself (brittle failure), and therefore the purpose of protecting the building pile foundation is achieved.
本发明公开一种提高软弱土地基中建筑桩基抗震性能的抗震结构及方法，属于建筑桩基技术领域。其主要通过设置浅层保护桩的方式来实现对建筑桩基的保护，浅层保护桩布置于所述建筑桩基的外围和/或布置于承台下方的建筑桩基之间，本发明在通过各种布置形式将浅层保护桩布设在建筑桩基外围及之间或布设于承台下，不仅可以提高整个建筑桩基的竖向承载力，且在地震过程中浅层保护桩能分担建筑桩基所承受的土体动力荷载，并可通过牺牲自身(脆性破坏)以消耗地震过程中的波动能量，从而达到保护建筑桩基的目的。
