某储罐基础在爆炸荷载作用下的受力分析

The force analysis of a storage tank on the load of explosion

通过对某储罐基础在爆炸荷载作用后的现场检测与有限元数值模拟,分析了储罐环形基础在爆炸荷载作用下的受力及变形情况,得出储罐在爆炸时引起的冲击力在环形基础外侧产生的较大拉应力是环形基础产生竖向裂纹的直接原因。

According to the field test and the finite element numerical simulation of a storage tank on the load of explosion, the paper analyzes the forces and deformation of the storage tank on the load of explosion, and concludes that the tensile stress in the outside ring-shaped base caused by the impact force in the explosion of the storage tank is the direct reason for the vertical cracks of the ring-shaped base.
