Limiting shock insulation and absorption system for main bridge and approach bridge of large-span cable-stayed bridge
The invention relates to a limiting, shock-isolating and shock-absorbing system for a main bridge and an approach bridge of a large-span cable-stayed bridge, and belongs to the technical field of large-span bridges. A longitudinal shock insulation support system is arranged on one side of the longitudinal bridge direction, and a bidirectional shock insulation support system is arranged on the other side of the longitudinal bridge direction; auxiliary piers are arranged at the bottom of an approach bridge main beam and the top of a bridge pier, longitudinal shock insulation support systems are arranged between the approach bridge main beam and the auxiliary piers and on one side in the longitudinal bridge direction, and two-way shock insulation support systems are arranged on the other side in the longitudinal bridge direction. The large-span cable-stayed bridge has the beneficial effects that the problems of large vibration, large displacement, multidirectional vibration coupling and the like of the connecting part of the main bridge and the approach bridge of the large-span cable-stayed bridge can be effectively solved, vibration in different directions is controlled, and particularly, mutual collision of the ends of the bridge is avoided; the device is simple, rapid and convenient to install, low in cost and good in limiting shock isolation and absorption effect, and the safety and durability of the structure are remarkably improved.
本发明涉及一种大跨斜拉桥的主桥与引桥的限位隔震减震系统，属于大跨桥技术领域，主桥主梁两端分别与引桥主梁设置接缝处，底部为桥墩；纵桥向的一侧设置纵向隔震支座体系，纵桥向的另一侧，设置双向隔震支座体系；在引桥主梁的底部，桥墩的顶部设置辅墩，引桥主梁和辅墩之间，纵桥向的其中一侧均设置纵向隔震支座体系，纵桥向的另一侧，分别设置双向隔震支座体系。本发明的有益效果在于能够有效解决大跨斜拉桥的主桥与引桥的连接部位振动大、位移大、多向振动耦合等带来的限位隔震减震困难，控制不同方向的振动，尤其是避免桥梁端部的相互碰撞，设备简单、安装快速便捷、成本低、限位隔震减震效果好，显著提高结构的安全与耐久性。
