- 摘要:
- 吊装直径较小的高耸烟囱具有一定难度，分段吊装可以减小其吊装吨位和吊装长度，化解不利因素。动臂桅杆的采用，减少了机具设备，扩大了桅杆作业范围，施工周期短，经济效益高。本文通过工程实例，介绍了动臂桅杆分段吊装80m钢烟囱的技术方案。
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): 17-19,2 收稿日期：1994-4-23分类号：TE682
