Supplementary instruction
I
(0.9, 1.0]
High degree of adaptability
The shield machine selected can satisfy the engineering requirements.
II
(0.8, 0.9]
Moderate degree of adaptability
The shield machine selected basically satisfies the engineering requirements. Engineers should do a good job in equipment maintenance, ground measurement and other related work.
III
(0.7, 0.8]
Low degree of adaptability
The follow-up risk of the selected shield machine is relatively large. It is necessary to pay attention to the performance status of the shield machine every day and to monitor the tunnelling of the shield machine at all times.
