摘要
无伸缩缝桥梁主要采用整体式桥台 ,其主梁、桥台和柔性桩基础构成一整体。对无伸缩缝桥梁进行受力分析时 ,要考虑梁、台、桩的共同作用、台后填土对桥台的作用以及土对桩的作用。本文提出了一个无伸缩缝桥梁的简化刚架受力模型。通过有限元程序对有、无伸缩缝桥梁的建模分析 ,初步得出无伸缩缝桥梁在静载下的受力特点 。
Jointless bridges consist of integral abutment.The beam,abutment and flexible pile serve as an interal system.It is necessary to analyze the interation among the beam,abutment and pile.Furthermore,we also have to conside the soil's effect on abutment and pile.This paper presents a simple rigid frame design model for jointless bridges.And with the finite element program,Ansys,the author analyzes a jointless bridge and a bridge with joint,and conclude the characteristics of jointless bridges under static loads for futher research.
