根据某柔性悬索桥的主要问题,提出了针对性的加固设计方案,其中主缆加固采用新型“吊拉组合体系”:斜拉索采用长短斜拉索对拉形式;斜拉索一端锚固于地面,另一端通过主塔顶部的转向装置锚固于加劲梁,且斜拉索在转向装置内可纵向滑动,减少斜拉索水平力对加劲梁和主塔的不利影响。
According to the main problems of a flexible suspension bridge, a targeted reinforcement design is proposed, in which the main cable is reinforced with a new type of “suspension and cable combination system”: the stay cable is adopted with long and short stay cables; the one end of the stay cables is anchored The ground and the other end are anchored to the stiffening girder by the steering device at the top of the main tower, and the stay cable can be longitudinally slid within the steering device to reduce the adverse effect of the horizontal force of the stay cable on the stiffening girder and the main tower.
