摘要
本文研究在地震力作用下桥梁横向挡块的极限承载力。总结国内外研究人员对桥梁横向挡块承载力极限值的计算方法和研究成果。通过手工计算和有限元软件模拟计算对比不同桥梁横向挡块在水平力作用下的极限承载力，分析影响桥梁横向挡块极限承载力的因素，为桥梁横向挡块设计提供理论依据。研究发现：桥梁横向挡块的水平承载力极限值与挡块的宽度、挡块的配筋方式、水平力施加的位置等因素有关。
关键词：桥梁横向挡块；水平承载力极限值；

Abstract
In this paper, the ultimate bearing capacity of bridge transverse block under seismic force is studied. This paper summarizes the calculation methods and research results of the ultimate bearing capacity of bridge transverse retaining blocks by researchers at home and abroad. Through manual calculation and finite element software simulation, the ultimate bearing capacity of different bridge transverse retaining blocks under horizontal force is compared, and the factors affecting the ultimate bearing capacity of bridge transverse retaining blocks are analyzed, which provides a theoretical basis for the design of bridge transverse retaining blocks. It is found that the ultimate horizontal bearing capacity of bridge transverse block is related to the width of the block, the reinforcement mode of the block and the position of the horizontal force applied.
