Cable-stayed bridge anti-seismic steel inclined strut and construction method thereof
The invention relates to the technical field of cable-stayed bridge main tower construction, in particular to a cable-stayed bridge anti-seismic steel inclined strut and a construction method thereof. The steel inclined strut is arranged between a left tower limb and a right tower limb of a diamond-shaped cable-stayed bridge, transverse connection of the left tower limb and the right tower limb is added, the overall rigidity of a diamond-shaped main tower is improved, and under the condition that a cable-stayed bridge bearing platform and the cross section and reinforcing bars of the main tower are not increased, the shock resistance of the cable-stayed bridge is improved; the cable-stayed bridge main tower comprises an upper tower column and a lower tower column, the upper tower column comprises a first left tower limb and a first right tower limb, the lower tower column comprises a second left tower limb and a second right tower limb, a second steel inclined strut, a third steel inclined strut and a fourth steel inclined strut are installed between the first left tower limb and the first right tower limb, and a first steel inclined strut is mounted between the second left tower limb and the second right tower limb; the first steel inclined strut and the second steel inclined strut are inserted anchoring type steel inclined struts, and the third steel inclined strut and the fourth steel inclined strut are surface anchoring type steel inclined struts.
本发明涉及斜拉桥主塔施工技术领域，具体为一种斜拉桥抗震钢斜撑及其施工方法，在钻石型斜拉桥左右塔肢间设置钢斜撑，增加左右塔肢的横向连接，提高钻石型主塔的整体刚度，达到不增大斜拉桥承台和主塔截面以及配筋的情况下，提高斜拉桥抗震能力的目的；所述斜拉桥主塔包括上塔柱和下塔柱，所述上塔柱包括第一左塔肢和第一右塔肢，所述下塔柱包括第二左塔肢和第二右塔肢，所述第一左塔肢和第一右塔肢之间安装有第二钢斜撑、第三钢斜撑和第四钢斜撑，所述第二左塔肢和第二右塔肢之间安装有第一钢斜撑；所述第一钢斜撑和第二钢斜撑为插入锚固式钢斜撑，所述第三钢斜撑和第四钢斜撑为表面锚固式钢斜撑。
