摘　　要：筒体顶部凹槽处为缓和应力集中，转角半径越大越好，一般取 １２ ｍ ｍ 左右。合理的转角半径应根据其具体结构，由应力分析计算出凹槽处的真应力，经过全面衡量来确定。For the purpose of reducing the stress concentration,the fillet radius for channel on the top of cylinder shell is considered as the more the better.Ordinary it is taken about 12 mm.The resonable fillet radius should be determined according to the concrete construction and the stress analysis to calculate the actual stress of the channel and in equilibrium all sidedly
