大跨径连续梁桥拥有受力强、长度长、伸缩量较好、合拢顺序多等特点,被广泛的应用在桥梁建设工程中,目前我国大跨径连续梁桥设计还存在很多的问题,例如跨中挠度较大、腹板开裂变形等问题,这都需要控制好相关结构设计问题,才能最大限度提高大跨径连续梁桥的质量和安全性。
Long-span continuous girder bridges have the characteristics of strong stress, long length, good expansion and contraction, multi-folding order and so on. They are widely used in bridge construction projects. At present, there are still many problems in the design of long- For example, a large mid-span deflection, web cracking and other issues, which need to control the design of the relevant structural problems, in order to maximize the quality and safety of long-span continuous beam bridge.
