摘　　要：在焦炭塔裙座上开设柔性槽能够减轻裙座刚度影响,降低裙座角焊缝处热应力。但同时柔性槽开孔处会引起较大的应力集中,同样会产生裂纹。为了使裙座角焊缝和柔性槽部位都能处于相对较低的应力水平,利用正交试验和数值模拟的方法,对焦炭塔裙座柔性槽参数进行了优化,对焦炭塔的设计和维护具有一定的实际意义。Grooving in the skirt of coke drum is able to lighten the stiffness impact on the skirt and reduce the thermal stress on its fillet weld. However, at the same time, it will cause considerably great stress concentration on the openings, and meanwhile it will crack. In order to keep the fillet weld of the skirt and the groove under a relatively low stress level, orthogonal experiment and numerical simulation method are used in this article to optimize the parameters of the groove. It has certain practical significance to the design and maintenance of coke drum.
