| 摘 要： | 介绍了桥梁结构施工中,在施工荷载、温度、混凝土的收缩与徐变、支座、偶然荷载以及人为荷载等因素的作用下,使得结构的内力出现重分布的现象,提出了结构内力重分布现象对施工及桥梁结构的不利影响及可能的控制措施,对工程实践中认识和避免结构内力重分布具有一定的意义.

| Abstract: | During bridges structure construction,many factors will induce internal force redistribution,such as construction load,temperature,creep and shrinkage of concrete,bearing,incidental load,artificial load and so on.Both the possible influence caused by internal force redistribution and the practical measures to avoid it are presented in this paper,to know and aviod internal fore redistribution in engineering practice. |
