A hybrid fuzzy evaluation method for curtain grouting efficiency assessment based on an AHP method extended by D numbers

作者：

Highlights：

• A hybrid fuzzy evaluation method for curtain grouting efficiency assessment is proposed.

• The proposed method can assess curtain grouting efficiency from the perspectives of both permeability and tightness.

• The D-AHP method can effectively represent and address uncertain information and make weighting more scientific.

• This study reveals that low permeability does not guarantee high grouting efficiency.
