茂名石化工业区一区北片火炬气管道的温度上限较高,支撑管道的管架高度在13.2 m到15.5 m之间,且茂名地区多台风.笔者运用CAESAR Ⅱ对管道的应力和管架的水平荷载、风荷载进行计算、设计优化.设计优化前,部分止推管架的水平荷载过大.设计优化后,止推管架的水平荷载降低至合理水平,使其外形合理美观,并降低了工程投资,取得了很好的效果.%The temperature ceiling of the flare gas pipeline at Northern Part of Manming Petrochemical Industrial Zone No.1 Area is higher, the height of pipe supports is between 13.2～15.5 m, and typhoon is frequent in Maoming area. The author used CAESAR II in the calculation and design optimization of piping stress, horizontal load and wind load of pipe supports. Before the design optimization, the horizontal load of some double-acting limit stops is too large. After the design optimization, the horizontal load of double-acting limit stops was reduced to a reasonable level, making its shape reasonable and beautiful, project investment was lowered, and achieved very good effects.
