Bridge expansion displacement control method
According to the bridge telescopic displacement control method, movable supports are installed between bridge piers and a beam body, the bridge piers arranged in the bridge direction are symmetrically arranged with the midpoint of the beam body as the center, and the bridge telescopic displacement control method is characterized in that hydraulic cylinders are installed on the pair of symmetrically-arranged bridge piers respectively, the two hydraulic cylinders are communicated through an oil way, and the hydraulic cylinders are fixedly connected with the beam body; and controlling two ends of the beam body to symmetrically stretch along the bridge direction. The hydraulic cylinders which are symmetrically arranged and communicated are used for replacing fixed supports between the bridge piers and the beam body, the hydraulic cylinders are connected with the beam body, hydraulic oil flows between the two hydraulic cylinders when the hydraulic cylinders move, the beam body is controlled to stretch out and draw back in the bridge direction, the two ends of the beam body stretch out and draw back symmetrically in the bridge direction, and it is avoided that the beam body stretches out and draws back in a single-side expansion joint; the expansion joint distance between adjacent beam bodies is reduced, the impact load of the bridge is reduced, the service life of the bridge is prolonged, and the safety and stability of the bridge are improved.
桥梁伸缩位移控制方法，在桥墎与梁体之间均安装活动支座，沿顺桥向排列的桥墎以梁体中点为中心对称设置，其特征在于：在一对对称设置的桥墎上分别安装液压缸并将两个液压缸用油路联通，液压缸与梁体固接，控制梁体两端沿顺桥向对称伸缩。本发明用对称设置并联通的液压缸代替桥墩与梁体间的固定支座，液压缸与梁体连接，通过液压缸运动时液压油在两个液压缸间流动，控制梁体沿顺桥向的伸缩，使梁体两端形成顺桥向对称伸缩，避免梁体伸缩位移集中于单侧伸缩缝，减小相邻梁体间伸缩缝间距，减少桥梁冲击载荷，延长桥梁的使用寿命，提高桥梁安全性和稳定性。
