Horizontal Force Analysis of Longitudinal Bridge Pier of Continuous Beam Bridge on Mountainous Expressway

文章介绍了预应力混凝土40 m连续T梁上部纵桥向水平力在下部桥墩上分配的计算方法,结合工程实际,并考虑桩-土效应,分析了在不同桥墩高差及不同桥墩尺寸下汽车制动力、温度影响力、结构收缩徐变影响力在桥墩纵桥向的分配情况及变化规律。

This paper introduces the calculation method of the distribution of the horizontal force in the upper longitudinal direction of the prestressed concrete 40 m continuous T-beam on the lower bridge pier.Combined with the engineering practice and considering the pile-soil effect,the distribution and variation law of the automobile braking force,temperature influence and structural shrinkage and creep influence in the longitudinal direction of the bridge pier under different pier height differences and different pier sizes are analyzed.
