Ultra-long stay cable damping device and cable-stayed bridge
The invention relates to a super-long stay cable damping device and a cable-stayed bridge, and the super-long stay cable damping device comprises a cableway pipe which is fixedly arranged on a bridge body; the two ends of the dampers are connected with the cableway pipe and the stay cable respectively, and the two dampers are arranged in the radial direction of the stay cable; the connecting supports are fixedly connected to the cableway pipe, the number of the connecting supports corresponds to that of the dampers, and the dampers are connected with the cableway pipe by being connected with the connecting supports. And the two dampers are respectively connected with the cableway pipe and the stay cable in the mounting vertical surface of the stay cable and in two directions vertical to the mounting vertical surface of the stay cable, so that in-plane and out-plane vibration of the stay cable can be effectively reduced. The inner tower wall and the outer tower wall of a cable-stayed bridge main tower are each provided with one ultra-long stay cable damping device, low-medium-high-order wind-induced vibration control over the ultra-long stay cable can be achieved through cooperative work of the ultra-long stay cable damping devices and the inner tower wall and the outer tower wall of the cable-stayed bridge main tower, and normal use of the ultra-long stay cable on a bridge body is guaranteed. In addition, damping devices of the inner tower wall and the outer tower wall are both installed in the main tower, and the bridge landscape is not affected.
本申请涉及一种超长斜拉索阻尼装置及斜拉桥，其包括：索道管，其固定装设于桥体；至少两个阻尼器，阻尼器两端分别连接索道管与斜拉索，两个阻尼器均沿斜拉索径向设置；连接支座，其固定连接于索道管上且数量对应阻尼器，阻尼器通过与连接支座连接实现连接索道管。两个阻尼器分别在斜拉索的安装竖面内以及垂直于斜拉索安装竖面的两个方向上连接索道管与斜拉索，使其可有效对斜拉索的面内、面外振动进行减振。在斜拉桥主塔的内塔和外塔壁上各安装一套上述超长斜拉索阻尼装置，通过两者的协同工作可实现超长斜拉索的低中高阶风致振动控制，保证斜拉索在桥体上的正常使用。另外，内塔和外塔壁的阻尼装置均安装在主塔内部，对桥梁景观无影响。
