| 摘 要： | 混凝土由于发生干缩、热胀冷缩，在荷载作用下会产生弹、塑性变形等，尤其高架桥钢筋砼墩身在施工中及竣工后，由于变形量较大，影响桥梁结构安全。因此对其变形量进行预估并加以运用，一方面可以指导施工，另一方面又可以使桥梁结构更加合理．延长使用期限。

| Abstract: | Because of dry shrinkage, expand when hot and shrink when cold, elastic deformation and plastic deformation will happen in concrete structure, particularly serious deformation often happen during or after the construction of viaduct steel concrete pier shaft, which may threaten to the structure safety. Some forecast and application viaduct pier shaft deformation will not only guide for the construction, but also make the bridge structure more reasonably and prolong its using life. |
