| Abstract: | The cause for the vault instability of a residual oil tank((5 000) m~3)was analysed with the outer pressure destabilizing theory.The result indicates that the negative pressure in the tank exceeds the limit of the critical load and distorts the vault.To ensure the safety of the tank,the management of the breather valve and flame arrester is strengthened by examining and repairing the tank and accessories in time so as to use it reasonably. |
