Large-span highway-railway dual-purpose three-tower cable-stayed bridge and design method thereof
The invention discloses a large-span highway-railway dual-purpose three-tower cable-stayed bridge and a design method thereof, and relates to the technical field of bridge engineering, on one hand, the cable-stayed bridge comprises a middle tower with a first height and two side towers with a second height, and the first height is larger than the second height; the middle tower and the side towers each comprise an upper tower column and a lower tower column which are sequentially connected from top to bottom, the upper tower columns are of a steel structure, the lower tower columns are of a concrete structure, the upper tower columns of the middle tower are connected with the main beam through a plurality of first stay cables, and the upper tower columns of the side towers are connected with the main beam through a plurality of second stay cables. On the other hand, the invention further provides a method for designing the cable-stayed bridge. The middle tower and the side tower are each arranged to comprise the upper tower column of the steel structure and the lower tower column of the concrete structure, so that the size of the whole structure can be reduced, the foundation scale is reduced, and meanwhile the concrete structure is prevented from cracking.
本发明公开了一种大跨径公铁两用三塔斜拉桥及其设计方法，涉及桥梁工程技术领域，一方面，该斜拉桥包括具有第一高度的中塔和两个具有第二高度的边塔，第一高度大于第二高度，中塔及边塔均包括由上至下依次连接的上塔柱和下塔柱，且上塔柱为钢结构，下塔柱为混凝土结构，中塔的上塔柱与主梁通过多个第一斜拉索连接，边塔的上塔柱与主梁通过多个第二斜拉索连接。另一方面，还提供用于设计上述斜拉桥的方法。通过将中塔和边塔均设置为包括钢结构的上塔柱、混凝土结构的下塔柱，从而可以减少整体结构的尺寸，降低基础规模，同时防止混凝土结构开裂。
