Novel composite pile bridge anti-seismic foundation in soft soil area and construction method of novel composite pile bridge anti-seismic foundation
The invention discloses a novel soft soil area composite pile anti-seismic bridge foundation which comprises foundation supporting piles, the foundation supporting piles are pile groups and are pressed into a soft soil foundation through a static pressure method, the soft soil foundation is compacted and reinforced, and a rigid pile composite foundation is formed; the upper structure is used for supporting or bearing a bridge collapse structure; the foundation supporting piles are used for supporting an upper structure, and fixed connection between the foundation supporting piles and the upper structure is cut off by laying a gravel composite layer between the foundation supporting piles and the upper structure. The gravel composite layer is fixedly arranged on the pile top, and an upper structure is supported above the gravel composite layer. The composite pile anti-seismic foundation cuts off fixed connection between the pile foundation and the upper structure, so that the bending moment of the pile body is reduced under the action of the seismic load, the response acceleration of the upper structure is reduced, and the natural vibration period of the composite foundation is prolonged.
本发明公开一种新型软土地区复合桩抗震桥梁基础，它包括基础支撑桩，所述基础支撑桩为群桩，通过静压法压入软土地基，并对软土地基进行挤密加固，形成刚性桩复合地基；上部结构，所述上部结构用于支撑或者承载桥垮结构；所述基础支撑桩用于支撑上部结构，所述基础支撑桩和上部结构之间通过铺设碎石复合层切断基础支撑桩和上部结构之间的固定连接；所述碎石复合层固定设置在桩顶，上方支撑上部结构。本发明的复合桩抗震基础切断桩基础与上部结构之间固定连接，从而在地震载荷作用下减小桩身弯矩，降低上部结构响应加速度，增大复合基础自振周期。
