Study on the Application of the Kent Index Method on the Risk Assessment of Disastrous Accidents in Subway Engineering

Table 7

Several key parameters.

Indexes	Score; scope	Notes
Basic index; Design index; Construction index; 𝐷𝑘; 𝑆𝑘	0–100; 0–100; >0; 50; 50	If the score is lower, the probability index is also lower. The construction index is unlimited, which shows that even though the basic index is not large, the possibility of an accident happening would still be high in poor construction conditions.
