摘要

摘要: 对正在开展的战略石油储备,提出用地中预应力混凝土罐进行石油储存.应用结构分析软件ANSYS对巨型混凝土单壁罐和双壁罐进行弹性分析,指出罐壁环向应力几乎全部由温度荷载造成,罐壁温度场和温度应力具有明显时间性,储油初期罐壁温差最大,96 h后罐壁顶部拉应力达到最大;设置中间保温层后,内罐应力减小,外罐应力增大,应对内、外罐连接支墩做特殊设计,以满足罐壁温度变形.

Abstract: A new vessel,the prestressed concrete (PRC) oil tank,for the strategic petroleum reserve(SPR) was represented. With the application of structure analysis software ANSYS, the distribution of the temperature and stress in the side wall of the oil tank was given,in which the stress is caused by the temperature,and the temperature and temperature stress changes with the time,and the maximum temperature stress happens at the top of the side wall at the early time of the oil storage. When filling the heat insulation layer in the side wall of the oil tank,the loop stress in the inner side wall reduces,and the stress in the outer wall increases. So in the design practice the joint of the inner and outer wall should be designed specially to satisfy the displacement caused by the temperature.
