现代斜拉桥设计一般采用平行钢丝拉索结构,该结构后期养护大,在中小城市中此桥结构可能成为城市的一种负担,而刚性连接的预应力混凝土斜拉板桥可以解决后期养护问题,同时也可为中小城市增添了一道风景线。 The design of modern cable-stayed bridges generally adopts the parallel wire cable structure, which is of great maintenance in the latter part of the period. This bridge structure may become an urban burden in small and medium-sized cities while the rigidly connected prestressed concrete cable-stayed bridge can solve the problems of late maintenance , But also for small cities added a landscape.
