摘要
以三峡水电站引水压力钢管施工现场为实例,研究取消伸缩节后焊接对引水压力钢管施工的影响,分析了两种方案在焊接过程中的变形规律,分别用经验公式和理论计算出两种方案焊接时的横向和纵向收缩量,然后分析收缩量对安装焊接过程的影响,选择出最佳安装方案。
Taking the example in the three gorges hydroelectric station, we researched the influence of the weld process on the construction and operation of penstock after moving contract-elongate nodes, analyzed the deformation law of two plans and calculated the crosswise and lengthwise shrinkage in weld process using experience formula and theory respectively, and then analyzed the influence of the welding and installing process on shrinkage ,finally chose the best installation plan.
