摘要
对1号机压力钢管与合拢焊缝焊接施工过程的拘束应力情况进行监测,了解和掌握拘束应力状况,为三峡左岸电站后续机组及其他同类工程施工提供依据。
According to monitor the constraint stress situation of 1# unit penstock and closured weld joint in welding construction process, we can understand and master the constraint stress situation to supply the foundation for the subsequent units of Three Gorges left bank power station and other similar project construction.
