Prestressing tendon 12 has very big allowance, though there are indivedual prestressing tendons 12 to fail, or even 5% prestressing tendon 12 is entirely ineffective
(such case can not possibly should occur), also only housing bearing capacity is declined slightly, and security is still guaranteed.
Until its service phase (at least 60 years) end, is the elastic expansion of housing first when super high pressure accident occurs, prestressing force
Beam 12 also has a small amount of increases by a small amount of stretchings, its pulling force.After internal pressure is increased to 1.2 times of rated operating pressures, as housing is continuous
Be expanded to armored concrete 11 crack, prestressed concrete pressure vessel inner surface sealing (when without using sealing Leak-tight liner when) open
Beginning local leakage.At this moment prestressed concrete pressure vessel internal pressure is far above its rated operating pressures and protection pressure.
When internal pressure reaches more than 1.5 times of rated operating pressures, the pulling force just meeting of the prestressing tendon 12 of prestressed concrete pressure vessel
There is very fast increase, it is (specified at 1.5 times when using Leak-tight liner is sealed that housing slip is quickly increased up the complete pressure release of housing
Under operating pressure, housing will not still leak), but the pulling force of prestressing tendon 12 still ensures tensile strength less than it
75%, at this time housing may many places cracking, prestressing tendon 12 is but still intact, and after dielectric leakage makes housing pressure release, prestressing force mixes
Solidifying soil pressure structure of container still keeps complete.
