Abstract EN

The vulnerability assessment model, composed by 11 vulnerability factors, is established with the introduction of the concept of “vulnerability” into the assessment of tunnel support system.

Analytic hierarchy process is utilized to divide these 11 factors into human attributes and natural attributes, and define the weight of these factors for the model.

The “vulnerability” applied io the assessment of the tunnel support system model is reached.

The vulnerability assessment model was used for evaluating and modifying the haulage tunnel #3207 of Bo-fang mine panel #2.

The results decreased the vulnerability of the tunnel support system and demonstrated acceptable effects.

Furthermore, the results show that the impact of human attributes on tunnel support systems is dramatic under the condition that natural attributes are permanent, and the “vulnerability” is exactly a notable factor to manifest the transformation during this process.

The results also indicate that optimizing human attributes can attenuate vulnerability in tunnel support systems.

As a result, enhancement of stability of tunnel support systems can be achieved.
