摘要
介绍了预应力混凝土曲线连续刚构桥施工控制的特点、原理和方法.根据有限元理论计算和施工过程中对主梁线形和内力的监测,为曲线预应力混凝土桥梁的安全施工和合理成桥状态提供技术依据。同时给其它大跨度悬臂浇筑连续梁桥的施工控制提供借鉴和参考。
This paper introduces the characteristics, principles and methods of construction control of pre-stressed concrete continuous rigid frame. Based on theoretical calculations with finite element method and the monitoring observation of the deformation and the stress of the main beam, technical data are provided for the construction safety and for the reasonable state of the erected bridge with curved pre-stressed concrete beams, which may be used as reference for the construction of other large span cantilever cast continuous bridges.
