新型开启桥的设计是以尽可能减少开启部分的结构重量为目标的。与传统开启桥相比,它采用了结构新颖,形态优美的无背索斜塔斜拉桥作为其开启结构,达到了平衡压重与结构的有机融合,并采用移动开合压重作为其开合方式,降低了对开启设备的要求。对于因主梁结构设计得轻柔而引起的振动问题,作了初步的探讨。 The new open bridge design is to minimize the structural weight of the open part of the goal. Compared with the traditional open bridge, it adopts a novel structure, beautiful shape without backsplash cable-stayed bridge as its open structure, to achieve a balance of weight and structure of the organic integration, and the use of mobile open and close pressure as its open Together, reducing the need to turn on the device. For the main beam structure design is gentle and caused by the vibration problem, made a preliminary discussion.
