Design method of multi-tower part cable-stayed bridge with unequal-height towers
The invention relates to a design method of a multi-tower part cable-stayed bridge with unequal-height towers. Side main towers, auxiliary middle towers, stay cables, transverse anchor cables, inclined anchor cables, a main beam, main beam weights, side main piers, auxiliary middle piers and side piers are designed. The side main towers are connected with the main beams through stay cables to be stressed. The auxiliary middle towers are connected with the side main towers through the transverse anchor cables and the inclined anchor cables, the rigidity and strength of the multi-tower part cable-stayed bridge are improved, and meanwhile the stay cables are connected with the main beams to transfer force. The side main piers, the auxiliary middle piers and the side piers support the main beam to be stressed, and the main beam ballasting plays a role in balancing the stress of the stay cables and the side main towers. The multi-tower partial cable-stayed bridge has the advantages that the multi-tower partial cable-stayed bridge with the unequal-height towers is formed in the mode that the small-height auxiliary middle towers and the large-height side main towers are combined, the small-foundation-size auxiliary middle piers are built in a deep water area, and the large-foundation-size side main piers are built on the shoreside or a shallow water area; the construction difficulty of the bridge is reduced, meanwhile, the spanning capacity of the partial cable-stayed bridge is improved, and the overall rigidity of the multi-tower partial cable-stayed bridge is improved in multiple modes.
本发明涉及一种不等高塔的多塔部分斜拉桥的设计方法，设计了边主塔、辅助中塔、斜拉索、横锚索、斜锚索、主梁、主梁压重、边主墩、辅助中墩、边墩；边主塔通过斜拉索与主梁连接受力；辅助中塔利用横锚索和斜锚索与边主塔连接，提高多塔部分斜拉桥刚度和强度，同时通过斜拉索与主梁连接传力；边主墩、辅助中墩、边墩支撑主梁受力，主梁压重起平衡斜拉索、边主塔受力作用。本发明的优点是：通过高度小辅助中塔和高度大边主塔结合的方式，形成一种不等高塔的多塔部分斜拉桥，基础尺寸较小辅助中墩建设于深水区，基础尺寸较大边主墩建设于岸边或浅水区，降低桥梁建造难度的同时提高部分斜拉桥跨越能力，并通过多种方式提高多塔部分斜拉桥整体刚度。
