大跨度连续梁线形控制施工技术

大跨度连续梁施工连续梁桥施工过程复杂，影响因素多。施工中对线形进行控制，是确保大桥最终线形满足预期目标的关键。线形控制是消除因设计参数取值的不确切所引起的施工中设计与实际的不一致性，在施工过程中对这些参数进行识别和预测是线形控制的关键。

SPAN CONTINUOUS BEAM ALIGNMENT CONTROL CONSTRUCTION TECHNOLOGY

large span continuous beam construction of continuous beam bridge construction process is complicated, many influence factors. To control the linear construction, is the key to ensure the bridge end line to meet the expected goal. Linear control is to eliminate inconsistent with the actual design the design parameter uncertainty caused by the construction, in the construction process of these parameters were identified and predicted linear control is the key
