针对某液化石油气球罐出现基础不均匀沉降的问题，通过对其支柱与球壳连接接头部位的应力测试，分析了该连接接头处的应力分布规律以及充装量和压力对接头应力的影响。结果表明，在该连接接头处，最大应力出现在连接接头的下端。随着液位的增加，支柱侧的应力增大，而球壳侧的应力变化不大；随着压力的增大，球壳侧应力线性增加，而支柱应力受压力的影响较小。
針對某液化石油氣毬罐齣現基礎不均勻沉降的問題，通過對其支柱與毬殼連接接頭部位的應力測試，分析瞭該連接接頭處的應力分佈規律以及充裝量和壓力對接頭應力的影響。結果錶明，在該連接接頭處，最大應力齣現在連接接頭的下耑。隨著液位的增加，支柱側的應力增大，而毬殼側的應力變化不大；隨著壓力的增大，毬殼側應力線性增加，而支柱應力受壓力的影響較小。

The stress distribution on connection joints of pillars with shell was analyzed ,the in-fluence of filling volume and pressure to the stress distribution were studied by testing the stress of a Liquefied Petroleum Gas spherical tank with pillar slanted on differential settled ground .The results show that the maximum stress occurs at the lower end of the connector ;with the increase of filling volume ,the stress on pillars side increased ;with the increase of pressure ,the stress on shell side increased linearly .
