Table 1

Corresponding relationships among health status, damage classifications, and maintenance measures.

Grades	Health status	Damage classifications	Maintenance measures	Processing requirements
I	Favorable	Basically intact	Routine maintenance	Measures should be taken to a few general members.
II	Ordinary	Slight damage	Minor maintenance	Measures should be taken to a few members.
III	Poor	Medium damage	Medium maintenance	Measures should be taken to most of the members, and measures must be taken timely to the individual members.
IV	Inferior	Heavy damage	Major maintenance	Measures must be taken timely to some members.
V	Dangerous	Close to collapse	Rescue maintenance	Measures must be taken immediately.
