Tower-free suspension bridge system and construction method thereof
The invention relates to the technical field of suspension bridges, in particular to a tower-free suspension bridge system and a construction method thereof.The tower-free suspension bridge system comprises a main cable and a main beam, the two ends of the main cable are connected with anchorages respectively, the main beam is connected to the lower portion of the main cable through slings, bridge abutments are arranged at the two ends of the main beam and support the main beam, and the tower-free suspension bridge system further comprises ground anchor cables arranged at the two ends of the main beam. The ground anchor cable is located on the outer sides of all the slings, one end of the ground anchor cable is connected with the main cable, the other end of the ground anchor cable is connected with the bridge abutment, and the ground anchor cable is configured in the mode that the line shape of the main cable can be kept stable by tensioning the ground anchor cable, the line shape of the main cable is controlled by tensioning the ground anchor cable, the line shape and stability of the main cable meet design requirements, and the overall rigidity of the bridge is guaranteed; the ground anchor cable is arranged on the bridge abutment, temporary construction measure application can be reduced, the mounting difficulty of the ground anchor cable is lowered, the existing bridge abutment is fully utilized, additional facilities are not added, the ground anchor cable can be arranged close to the main beam, and the effect of improving the stress of the bridge structure is good.
本发明涉及悬索桥技术领域，特别是一种无塔悬索桥体系及其施工方法，包括主缆和主梁，主缆的两端分别连接有锚碇，主梁通过吊索连接在主缆下方，主梁两端设置桥台，桥台支撑主梁，还包括地锚索，地锚索设置在主梁的两端，且地锚索位于所有吊索的外侧，地锚索一端与主缆相连接，地锚索另一端与桥台相连接，地锚索被配置为：通过张拉地锚索能够维持主缆线形稳定，通过张拉地锚索来控制主缆线形，使主缆线形和稳定性符合设计要求，保障桥梁整体刚度，将地锚索设置在桥台上，可减少施工临时措施应用，降低地锚索安装难度，即充分利用既有桥台，不增加额外设施，又能使地锚索靠近主梁布置，对改善桥梁结构受力效果较好。
