Multi-tower cable-stayed bridge
The invention relates to a multi-tower cable-stayed bridge, and relates to the technical field of cable-stayed bridges. The cable-stayed bridge comprises a main beam, a plurality of cable bent towers and a plurality of stay cables, the plurality of cable bent towers are fixed on the main beam, and the plurality of stay cables are used for connecting the plurality of cable bent towers with the main beam; the plurality of stay cables comprise 2N combined stay cables used for connecting at least one middle cable bent tower with other cable bent towers, and N is a natural number; the 2N combined stay cables comprise shape memory alloy beams. According to the cable-stayed bridge, the middle cable bent tower is connected with other cable bent towers through the combined stay cables comprising the shape memory alloy bundles, horizontal displacement of the tower top of the middle cable bent tower can be effectively restrained, and meanwhile the anti-seismic property of the cable-stayed bridge is improved.
本公开涉及一种多塔斜拉桥，涉及斜拉桥技术领域。上述斜拉桥包括：主梁、依次排列的多个索塔以及多条斜拉索；多个索塔固定在主梁之上，多条斜拉索用于连接多个索塔与主梁；多条斜拉索中包括2N条组合斜拉索用于将至少一个中索塔与其它索塔连接，其中，N为自然数；2N条组合斜拉索包括形状记忆合金束。应用本公开利用包含形状记忆合金束的组合斜拉索将中索塔与其它索塔连接，可以有效约束中索塔的塔顶水平位移，同时提高斜拉桥的抗震性能。
