拱座变位对结构内力的影响分析

The Affect Analysis of An Abutment's Change to The Internal Force of Structure

刚架拱桥拱座变位的原因有很多,利用计算机软件及其建立的模型对昭通市刚架拱桥拱座的水平变位和竖直变位进行计算和对比分析,变位时轴力、剪力、弯矩以及各个节点的水平位移、竖直位移、转角位移都呈现线性增长的趋势,变位越大,产生内力值也越大。尤其是轴力和剪力,竖直变位增长量要比水平变位的增长量要大的多。

Rigid frame arch bridge abutment deformation of the reasons,the use of computer software and the established model of the rigid frame arch bridge abutment Zhaotong City,the level of deformation and vertical deformation calculation and comparative analysis of deformation,when axial force,shear force,bending moment,and each node horizontal displacement,vertical displacement,angle displacement were the only linear growth trend,the greater the deformation,resulting in the greater Neili Zhi.In particular,axial force and shear force,vertical deformation than the level of growth in the amount of growth in the amount of deformation to a large number.
