- 摘要:
- 本文对长输管道铺设焊接时所产生的提升应力进行了深入的分析，推导出计算某一横截面提升应力的公式，编制了一个专用计算机程序，用计算机分析钢管在施工中所受提升应力，绘出提升应力与提升高度之间的关系曲线。
The lifting stress caused in welding long distance pipeline is detailedly analyzed and a formulafor calculating the lifing stress on any across section is derived. A typical program for calculation with computer is also compiled. The Lifting stress on commonly used steel pipes is analyzed with computer and a curve showing the relationship betwean the lifting stress and the lifting height is drawn out.1994,5(5): 12-16,2 收稿日期：1994-5-23分类号：TE973.3
