| 摘 要： | 大跨径预应力混凝土连续刚构桥梁目前常用的施工方法是悬臂浇筑法，为保证大桥的合拢精度以及大桥成桥后的线型符合设计要求，必须对大桥施工各梁段的立模标高进行有效控制．本文以螺丝岭大桥为背景介绍了施工控制中的挠度计算方法及监控实施方法，可为今后同类型桥梁的施工控制提供借鉴．

| Abstract: | At present, cast-in -place cantilever method is mainly used to construct the long span prestressed concrete continuous rigid-frame bridges. To make sure the folded precision and the linear of the bridges is accord with the demand of design, measures must be taken to control the forms elevation of each section of the beam effectively during the construction . Deflection calculational methods and the monitoring way of construction control, which can provide the model for the next similar bridges construction control, is introduced in the text in the case of Luosiling bridge. |
