摘　　要：法兰连接结构火炬塔架一般采用分节吊装,本文提出一种法兰连接结构火炬塔架整体吊装技术方法的创新。利用CATIA对火炬塔架整体进行100%实体建模,使用CATIA有限元分析模拟火炬塔架整体吊装时的水平和竖直两个极限状态工况,对吊装时塔架的强度和稳定性进行校核计算,查找出危险点及提出薄弱结构的加固处理措施,为吊装工艺设计和方案制定提供依据。Segmentation hoisting is generally used for flare stack with flange connection structure. This paper presents a technical innovation of integral hoisting of flare stack with flange connection struc- ture. In the paper, CATIA finite-element-analysis is used to build 100% model of flare stack and to simulate working condition in both horizontal and vertical limit states. During the integral hoisting of flare stack, strength and stability of flare stack during hoisting are checked and calculated. Dangerous points are found. Measures of strengthening weak structure are proposed and reference is provided for hoisting procedure design and formulation of hoisting plan.
