预应力连续梁施工监控关键技术研究

摘要

Based on the monitoring project of cantilever pouring of a pre-stressed continuous beam in the province, this paper studies the influence of construction load on the alignment and cross-section stress of the main girder during cantilever pouring, and analyses the key technology of monitoring the alignment and cross-section stress of the main girder during the monitoring process of cantilever pouring of the continuous beam, so as to complete the construction of the bridge.It is of great significance to meet the predetermined requirements.%以省内某预应力连续梁悬臂浇筑施工监控项目为背景,研究了悬臂浇筑过程中施工荷载对主梁成桥线形及截面应力的影响情况,分析了连续梁悬臂浇筑施工监控过程中主梁线形及截面应力监控的关键技术,对成桥工况满足预定要求具有一定意义.
