摘要
桥台是整个桥梁结构不可缺少的构件之一。振动对液化区土体的影响较大,会降低土体的承载力,位于液化区桥台的最主要破坏形式就是滑移破坏。当桥台发生滑移时,会影响到桥梁的整体工作性能。从能量转化的角度,采用链式破坏的理念分析地震作用下桥台滑移破坏的机理。
The abutment is one of the important components of bridge structure. The effect of vibration to the soil on liquefied area is larger, and can reduce the capacity of the soil on liquefied area. The main failure mode is slipping damage. When the abutment destroys, it will affect the overall working performance of bridge. From the angle of energy conversion, using the concept of chain destruction, this essay analyses the mechanism of abutment slipping damage under the action of earthquake.
