8. The method of claim 5, wherein,
if the result of the evaluation is: and determining that the shield subway tunnel segment needs to be reinforced when the shield subway tunnel segment is subjected to the event of corner collapse and block falling, or the event of water leakage, or the event of slab staggering.
9. A scanning detection device for shield subway tunnel section of jurisdiction includes:
the acquisition module is used for acquiring the form data of the shield subway tunnel segment;
the evaluation module is used for carrying out deformation evaluation on the shield subway tunnel segment according to the form data so as to obtain an evaluation result; and
and the determining module is used for determining whether the shield subway tunnel segment needs to be reinforced or not according to the evaluation result.
10. A non-transitory computer readable storage medium having stored thereon computer instructions for causing the computer to perform the method of any one of claims 1-8.
