Multi-tower continuous span cable-stayed bridge
The invention discloses a multi-tower continuous span cable-stayed bridge, which comprises N continuous spans, wherein the continuous spans are sequentially connected, each continuous span comprises a main beam, M bridge towers and a plurality of stay cables, the stay cables are used for connecting the bridge towers and the main beam, N and M are natural numbers, the N is greater than or equal to 2, and the M is greater than or equal to 3. The multi-tower continuous span cable-stayed bridge has the advantages that in each continuous span, the main beam is of a continuous structure, and a rigid hinge is arranged between every two adjacent spans and is used for releasing the longitudinal relative linear displacement of the main beam, so as to solve the problem of temperature effect of the long main beam; one bridge tower adjacent to each rigid hinge is of a four-leg vase-shaped structure, so as to improve the vertical rigidity of the bridge and reduce the bridge tower foundation scale; the middle bridge tower is provided with a longitudinal and transverse elastic restraint device and a transverse dynamic damping device, and the other bridge towers are provided with longitudinal and transverse dynamic damping devices and transverse elastic restraint devices, so as to improve the longitudinal and transverse static and dynamic stress properties of the bridge. The vertical rigidity and the static and dynamic stress properties of the multi-tower cable-stayed bridge can be effectively improved, the foundation scale is reduced, and the economy is better.
